2014-2018 Sierra/Silverado Flickering or Shutting Off...Ground Issue SOLVED!
ฝัง
- เผยแพร่เมื่อ 20 ก.ค. 2021
- I'm sure that no one here likes their vehicle straight shutting off or even flickering when you're driving it.. so we had to fix that ASAP! My truck, fortunately, didn't shut off at a high speed but at lower speeds (5-15 mph) would flicker all the electrical components, and then it SHUT OFF completely when I was backing up in my driveway. So these two fixes SHOULD prevent any more ground issues with your truck.
FYI THIS IS NOT FOR EVERY CAR OR TRUCK. THIS IS A RECOMMENDATION ON THESE SPECIFIC YEAR TRUCKS. THIS ALSO MAY NOT FIX ALL OF YOUR ELECTRICAL ISSUES, MAY YOU HAVE MORE.
(Alright, no more all caps :) )
As always, thank you for the support and encouragement, it is much appreciated. I hope this helps!
Many Blessings. - ยานยนต์และพาหนะ
Had the same issue even after cleaning passenger side frame ground. I added a third ground cable between the battery and the support bar above. No issues for 6 months. Just make sure any new ground cable follows the other two through the ground sensor ring.
My 2015 started messing up on power steering randomly . The ground on left side was definitely dirty. Truck is running with no issues after cleaning and retighten . Thanks for this video. Helped out alot
Awesome brotha! Thanks for watching!
My 15 started flickering and my power steering would shut off when making sharp turns. I did the dash ground point mod. Then I replaced the battery ground cable. Then I upgraded my battery. My 15 Rado has been running strong for over a year now with no electrical issues.
Was the steering wheel jerking out of your hands ?
@@brandondecoste8794 not jerking. Just noticed the power steering was out when I tried turning the steering wheel.
Mine jerks out of my hand and it stalled out on me after trying to turn my wheel 5 times.
@@brandondecoste8794 do the dash lights turn off and on and does the stability track notice come on?
@@jrchevy2500 yes
Thanks for this video Hunter! It definitely helped. I cleaned off the chassis ground / frame and then added some dielectric grease before reinstalling. I also pulled apart the dash and was able to get to the ground G218. Someone in this thread mentioned removing the speaker for easier access and that helped a ton. I was able to fit a mini 10 mm wrench in there. I didn't have the foam issue that everyone was talking about (foam wasn't touching the ground or stuck in the ground) but I did notice it was loose. So I added some dielectric grease and tightened it down. I've spent the last week trying to recreate the electrical issues from before but so far your method has worked! I'll update in this thread if that changes.
Of course, Ryan! Good call on the dielectric grease, I’ve used it on some my secondary terminals attached to my battery. Didn’t think about it back then which probably would’ve been a good idea. Good on ya tho! But yes please let us (me and everyone who needs help) know how it has worked for you! Knowledge is currency.
Have you had the electrical issues since? Been having this issue too but its intermittent and happens like once a month
@@xredoptixnotpro8168 no I haven’t had this issue at all since I fixed it. I think the main issue was that the ground underneath the dash was loose.
Thanks guys ! I’m going to try this fix . My 16 Sierra is pulling the steering wheel from my hand 🥲
If there is a ground issue, you can have multiple issues with any electrical on your vehicle. The power is looking for a ground so it could run through your radio it could be your brake lights it could be your traction control or anywhere else. Remember there is a ton of electrical on these things overtime the corrosion will win wire brush and dielectric grease does wonders.
I just did that to my truck I hope it works also 10mm wrench works with the ground bolt under the dashboard
Perfect fit on my "18 GMC Sierra 1500. I was having all the same issues. Removed and tightened the A-pillar ground and then I did the driver-side chassis ground, which I'm quite sure was the main grounding issue. It was corroded like yours and had lots of grime around it. Cleaned the battery ground contact, bolt, and chassis holes with a wire brush and haven't had any issues since. Thank you!
Awesome! Great job. God bless!
Hunter.... my guy.... you saved me. I replaced my battery and alternator before I did this. A year of frustration is hopefully resolved!
I hope it works out for you! Lmk if it still acts up cause I have one more solvent for this issue
@@hunterrwiilsonhey hunter, whats also the other tip you have to solve this issue ?
@@josephfuentes02 opening up the distribution box on top of the battery, and disconnecting and cleaning those ground connections. I even applied some dielectric grease to them before tightening them back down
@@hunterrwiilsondo you have any socials to send you a picture of the distribution box lol, i don’t want to mess anything up
@@josephfuentes02 yeah they're in my bio or whatever TH-cam calls it lol, but my IG is @hunterrr.wiilson.
But that box sits directly on top of the battery. There's some clips on it you pop off and you'll see the other grounds and such. Make sure you disconnect the main ground from the battery too.
I had the problem of the radio changing stations on its own. It would go through everything that it was capable of doing. Then go into navigating. I looked at google and yahoo and got as many answers as there are leaves on a tree. The dealer put in a new screen. I thankfully bought the extended warranty. 2017 Silverado Ltz 12,000 miles on it . Last year when I got it. The screen came up on cures a couple of times. The service tech said that this happens a lot. Even on some of the Fords. Other than that I’ve had no other electric problems. I did replace the battery it was the original one. I think I’ll do what you did anyway. You made it look easy enough even I could do it. They suggested to keep the screen clean. There’s stuff for computer screens at Office Depot and Best Buy, but don’t use glass cleaner or anything with alcohol. Just wipe easy with a microfiber towel. Hope that he knows what he’s talking about.Seems like this has been a Gremlin in the system for a very long time. Surprised that there wasn’t a recall years ago.
The entire reason the trucks have bad ground under the dash is the bolt is screwed down on the insulation. If you don't completely remove the bolt and get it out from under it tearing it does nothing.
Can't wait to get rid of this 14 Sierra, great video btw I had the same issues along with 10 others, never again General Motors....never....
I love my truck, but man not its problems
i have a 2014 gmc sierra, i have done all the grounds and it made things better, but for anyone still experiencing issues i have found that the factory negative cable can also be the problem even if it looks perfect. you may be able to add your own ground and run it through the loop sensor and fix any remaining issues or just get a new factory cable. i have even seen it where a guy cut off the negative clamp and replaced it with a copper lug and solved the issue when doing a voltage drop test. hope this helps anyone like me where these didnt fix it completely
Good tip sir. I also found that cleaning, tightening, and applying diaelectric grease to the extra cables in that box on top of the battery helped too. Did this only a few months ago so it didn’t make the video.
Just put that same intake on my 2014 lastnight lol.. sounds great with the muffler delete
Just an fyi and maybe it's been said but you don't have to disconnect the battery when dealing with grounds.
So I'm doing this right now. If you remove the speaker you can squeeze a wrench on it easy. I recommend getting a cheap 10mm ratcheting wrench from Harbour freight (princess auto) and you will have to put a slight bend at the end
Someone may have already mentioned it but if you remove the two screws and connector on the speaker it slides right out. That gives access to get a wrench on the nut.
Wish I would’ve thought of that back then 😅
What size wrench do the speaker screws take?
@@richburley5670 I believe it was 8mm. You'll want to use a 1/4" ratchet and socket though. It'll be tough to get a wrench there unless you have an offset box set.
@@dlm339 I just fixed it today. It turned out to be 7 mm and it made the job a lot easier, that's for sure. The driver's side ground on my truck had insulation trapped under the ground clip. The passenger side one was just loose, it have never been tightened down from the factory. This appears to have fixed my problem, even the service engine soon light went away.
Thanks to my wife she found you and this. Chevy service alert does not address this secondary ignition ground. Also, your truck looks like most underside. We do the beach and bunch of 4x4, so yup, i checked all other possibilities, but not the one by the speaker. Will update after i address. 2017 silverado z71 was at the dealership for 1 months and they fixed all other bs, but nothing to address this.
Hoping it works out for you! Thanks to you and your wife for watching!
my 15' Silverado was shutting off randomly. At slow speeds or while accelerating at low rpm's. AC would also shut off, Radio would stay on. Initially, I cleaned the ground connections under the passenger AND driver side with a wire brush. (Very easy to do). The next day, the truck stalled again while pulling out of a parking lot. After further research, i followed instructions on (Bulletin No.: PIT5405C) google this bulletin, it references a lot of the issues people are mentioning in the comments!!!! After removing both tweeter speakers, i was able to remove a good chunk of rubber/deadening material. from the ground G218. the right side was in direct contact underneath the ground. Hopefully this fixes the issue, if not next step is to replace battery cables.
Did you end up changing the battery cables?
You saved me a trip to the dealership!! Thankyou!!!
Of course!
Just had my steering lock up last night for the first time while backing into garage (screens black, heavy shudder, engine nearly dying) I'm going to try this this weekend. I have been having intermittent screen changing both on radio and on the small screen in front of steering wheel for a long time, do you think that could be related? I know with electrical it's all related to some degree, but excited that this may be a fix. Very well done video on your editing and camera angles! Thank you
Thank you! Try this fix first to see if it does the trick for you, if this doesn’t fix your screening issues there’s a plug behind the glove compartment that has a stupid sharp angle from the factory and could be coincidentally giving you issues too. If you get back there and unplug it and plug it back, that may help. There’s some videos out there but the plug is blue I believe
@@hunterrwiilson ok, thank you again. I will keep that in mind. steering wheel issue much more pressing issue. Have a long weekend and I'm excited for the project especially after having watched your vid.
@@BEASTIE51 of course! Oh and for sure, I didn’t touch my truck until I fixed that issue, it’s a pain but guess we gotta roll with these gm punches
Would these grounds be the problem if the truck has no electrical power at all?
Is it possible this bad ground could cause the high beam on my 2014 Silverado to stay stuck on? Even after shutting the truck off they stay on, have to disconnect the battery to get them to shut off…
Gonna have to give this method a try. I have been having the same issue that has gotten worse. Died while on the freeway. I noticed the dash was flickering and wanted to make the nearest exit and it died. I had enough momentum to make my exit and pull into a parking lot right off the exit. I just pop the hood and jiggle the ground a bit. It usually dies when I am going slow or making a slow turn. Sucks when it happens at a stop sign or light because I can't even turn my hazards on because there is no electricity. It baffles me that there has not been a recall on this as I have seen many others have the same issues. If there was a recall on this, feel free to make me look like a fool.
I’ve also used some dielectric grease on my secondary terminals attached to my battery. Didn’t think about it back then which probably would’ve been a good idea. So try this method, and make sure all grounds are tight. Any gap or wiggle will cause a break in the circuit and result in no power.
This EXACT same thing just happened to me yesterday- did you find a solution/did this one work? Thanks in advance!
This just happend to me last night headlights went out and flickering glad I found this
2018 Chevy Silverado. Yeah same thing here for the past two weeks. Service Stabil Trak and Roll down window message. Mine still under a warranty but they (Dealership) are only covering the positive cable replacement. So going to try the cleaning ground contacts.
Exactly why I just hop on Dr. Google and figure it out myself, dealerships don't really help too much
P
So did that work for u? Mine is doin the same rn
@@joeroe2839 yes it did. Have not had any issue since then.
I have a 2018 too, did the me dash insulation, happened again after a month, had the battery, alternator and charging tested and everything is good. Just gotta do this trick in the video
My truck started acting up today doing the exact same thing, left to work at 5am & headlights turned off & so did the dash followed by my steering wheel locking up on me as I was trying to switch lanes. It was very scary luckily there were no cars close to me & I was able to pull over turn it off & back on.
Definitely give this a try to be safe!
Just remove the tweeter to gain access to the ground. There is one behind each passenger and driver tweeter in the dash. 7mm screws to remove.
Do you know what the clip on the driver side is called. I broke mine putting back in and trying to find the clip to buy another one. And the ground tricked helped my flickering issues thanks man
Idk what clip you're referring to lol, but I'm glad this helped!
Hunter? So I scrolled and read many of the comments, I’m just curious did your radio display go black as well ? My situation is my lights began very slightly flickering then when I when to roll my window down the headlamps completely went out but only as long as I would hold the switch I was on the interstate so I’m not sure if the power steering actually cut out but when I arrived home when I tap my brake it would go out but not as I applied it to stop but only tap. Not sure if that makes much sense but I was wondering what all was actually happening I appreciate it time an thanks in advance
It seems to me that all of your issues are heavily affected by the grounds. Since most of the truck, even the power steering, is electric, one short or mishap will throw the entire truck off since there’s a running ground loop around the truck. Dig into these ground fixes and see if that helps
Recently, my horn sensor started going off randomly saying that my hood was open, my subs started going out and coming back on, the steering wheel would briefly lock when turning at low speeds. That hood sensor goes off like crazy when I turn my radio up and that bass hit. This makes me think that I have a loose ground somewhere. I bought a ground cable from O'Reilly's, but prior to changing it, I'm gonna try to clean these ground points. I hope it works.
Check out the distribution box on top of the battery too, clean the grounds in there too and apply some dielectric grease. But yes I would definitely clean these grounds and see what happens. Hope this helps!
2014 Sierra here. All terrain edition 33’s on a 5” lift. After Dealer changed the engine (blew up on me after 6 months) I’ve had multiple issues since she returned to me. Recent weeks, subwoofers will cut out, loss of power to radio, “service stabilitrak” comes on then goes away momentarily. Will be checking grounds tomorrow.
Definitely check out these grounds but also check the connections inside that smaller box that sits on your battery. You'll see it has bigger gauge wires coming out of it. I cleaned those connections and put some dielectric grease on them. Tightened them down well to make sure no gaps and the grease will make sure no moisture messes with the connections.
I've been having an issue with the headlights pulsing/flickering ever so slightly. The new battery did nothing to solve the issue, thought maybe it was an alternator issue but that seems to be charging just fine. No other issues other than just headlights, so I might have to check that frame ground for connection issues.
Check your connections inside the distribution block (small black on top of your battery) to see if that is effecting you too. I cleaned the connections and applied some dialectic grease on them before tightening down.
2014 GMC Sierra owner here and it is just my headlights that flicker and then go out. If I pull over and turn the truck off and then back on again, the headlights come back on. I replaced the battery and still have the problem. I'm gonna clean the ground connections like you showed. If that doesn't work, I'll replace the battery cables. If that doesn't work, I'm driving it off a cliff@@hunterrwiilson
Hey Hunter is been over a year since posting, how’s the truck running? Planning on doing this tomorrow if yours is still running well
Haven't had any issues with these two grounds since! I do recommend putting some dielectric grease on those two grounds just to ensure there is a strong connection. Something a person commented that they did and it's a really good idea!
The issue that I am having, is that the dash lights if there are not them, they do flicker somewhat ever-so-slightly. The other day, my AC took about 10 minutes to start blowing cold air. Lastly, the other day my radio did not seem to have a display, although when I looked at it in the nighttime, I could see that it was lit up. I did verify that the fuse was okay on the radio circuit. I am hoping that these two ground issues will cause my issue to go away. Lastly, when the dash flickers, the AC seems to go in rhythm with the flicker.
Seems like you need to give these two grounds out along with the other ground on the other side of the dash. That one is responsible for the AC. Clear those three grounds and see what it does for you!
@@hunterrwiilson I absolutely will give that a shot. Thank you. By the way, is the other ground on the other side as accessible as the driver side?
@@dennisranck1613 of course! Glad I can help if any! Yeah it should be just as accessible as the driver side
Did stability track light or steering assist and ac dying down aswell when the issue was occurring ?
Well when it all shut down the system tweaked and popped up some nonsense until I restarted the truck. Your AC problem may be the ground on the passenger side in the dash. Try fixing that and see if it helps. That’s allegedly the AC ground point.
Hello, 2014 silverado same issues but my problem was at the fuse box under the hood, found a lot of corrosion under it used wire brush and dielectric grease problem fixed, I did try the ground wire like you did but that didn’t solve it,Thanks
Howdy! Uh, yeah I’m not 100% sure what else could be the issue. So you did both ground fixes correct? But I’ve heard some other guys in the comments who’ve said replacing their ground wire or adding another ground helped. But I know this sounds obvious, check how tight your battery connections are. Any space could short the truck out.
Check out Mr. John T Flaim’s comment and see if that helps also. Seems like a very knowledgeable gentleman
Anyone reverse dash ligh flicker and M not engaging I feel like it could be a electrical problem or transmission just giving up
I have a similar issue out of my 2014, to where you’ll go to slow down to turn & the whole truck will shut off. A/C, radio & all. Coast to a stop, put the truck in park & restart it & a message reads “roll passenger side window down.” Hoping this fixes my issue as I’ve done the ground wire behind the passenger side wheel & no luck.
Yeah it’s a scary and annoying thing these trucks do. This has worked for me till this day, so I’m hoping it works for you
@@hunterrwiilson wow so even a year later & it’s still working ? I just bought my truck back in March & it’s done it twice. You ever have problems with the AC shutting off randomly for like a minute & then coming back on ?
@@ryandurham5725 I haven’t had issues with the AC besides having to replace the condenser.
@@hunterrwiilson what were the issues you had with the AC when you had to replace the condenser if you don't mind me asking. I'm having a lot of issues where the AC will be blowing perfectly fine & then just completely cut out & black out the screen. Then a couple minutes later it comes right back on in its normal state.
@@ryandurham5725 mine was a crack in a weld on the condenser. Very common in our year models.
What it sounds like for you is a ground issue. So just as you saw me correct and fix the ground on the drivers side, do the that same process to the passenger side ground in the dash. That, allegedly, is what the AC is grounded to. So I’d give that a shot and see what happens.
My 14 cluster keep flickering when i press the brake pedal or while im driving . Is the ground under the dash the problem?
Possibly a ground issue. Or some sort of short somewhere. Electrical work is hard to track. So just start with the most simple solution and progress up from there
OK... So I had all the same general issues. But when I tried to do the "Clean-up" fix of the 2 ground lugs under the dash cover I just could not get at them. No way could I undo the connection and clean the area. Plus I do not really buy that the coating is the problem. ANYWAY... What I did and it COMPLETELY solved all the strange electrical issues and it has not stalled again is run a new "Ground-Bus". Even with the very limited access I was able to secure a crimp-on wire loop terminal on top on the existing ground stud with another nut. I used #8 AWG wire (10AGW likely OK) from the driver side over to the passenger side and then down via the lower passenger side interior kick cover to the main frame/chassis ground lug as shown in many videos. This new ground bus between the two under dash cover ground lugs and to the frame ground fixed all these strange electrical issues. Hope this is helpful info. It has now been almost a year and all is still working well.
Sounds like a solid solution! You’d probably have good traction if you made a video on this
@@hunterrwiilson I'm not a video guy and enjoyed yours. Feel free to use my info for any new update by you.
@@johntflaim9924 fair enough. I’ll be sure to inform others if they want to try another solution!
Forgive my ignorance, but what's a ground bus?
@@DanRivas04 A BUS in electrical talk is just a common point that a termination is connected to. In industrial control systems there is always a Ground BUS Bar, a heavy gage copper bar that ALL ground leads/wirers are connected to so they ALL have the same ground point/potential. So I ran a heavy gage copper wire from the driver side to the passenger side and then down to the frame ground lug/ point. In this case the truck frame is the Bus Bar/ common point. I hope this helps. Sorry for being so late.
Issue just happened to me tonight. Gonna go try this out when I get home. Hope this does the trick. 🙏
Hope you’re safe man. It’s honestly frustrating to see how common this issue is. I think this video is up to 93k views. Can’t believe 93k people have had the same issue. Crazy. Lmk if if works out for you!
@@hunterrwiilson Thank you bro. Made it home safe. I’ll keep you posted.

Update
Hey hunter I’ve been havin g a problem with my sound my radio , door chimes,or turn signals won’t make a sound it jumps on randomly until I turn my it off and also my lights flicker
Then I'd start to look a little more into your situation. So go check all connections on the battery and inside that little box on top of the battery. You can try these solutions out as well, but it sounds like you may have some bad grounds elsewhere.
i got same issue. my husband driving it on interstate and my 15 suburban power steering just stopped working and flickering. it was scary, not safe at all. is the ground wire u cleaning passenger side or driver side
Oh wow, I hope y'all are okay! The ground wire is on the passenger side, behind the tire, and on the frame.
@@hunterrwiilson yes we were ok. luckily we were able to pull over. turn off the car then turn it back on then ot worked again. ill definitely check it out
Hello by any chance did you have a (radio static) sound coming from your audio speakers before this was done to your truck??
I don’t think so
My truck is jerking the wheel out of my hand and I took off the 2g18 or what ever it's called and cleaned the one under the passenger side on the body and put grease on it but still no fix. Going to try to change the neagitive cable next 3rd times the charm right.
Let’s hope so! But if the changing of the negative cable doesn’t work then I’d look into what the dealership has to say. Maybe you can fix whatever they recommend
Same thing w mine did u get it fixed
hows the truck running?
@@carnz06 it fixed it for a while but it just did it again 3 times than stopped i think the ground under the passenger side is a terrible spot i am going to change it as soon as it warms up out.
Question for you: were you experiencing messages that said the park assist was not working? And then the truck shut off? I cleaned the bottom ground wire. But it happened again. Wondering if the ground wire by the windshield will fix the problem?
I don’t remember that message popping up. I just remember my truck glitched and then as I backed into my driveway it cut straight off. There’s a possibility that fixing the dash ground could help, but also could be a main ground issue. Electrical’s can sometimes be a pain to track down. Coming from an electrical engineer lol
Did you end up finding out the problem just happened to me
@@acast6961 battery connections/cables were bad and needed to be replaced
@Ryan no ground issues, just bad battery cables?
@@dmalin7042 correct. I had to replace the battery cables and haven’t experienced any issues since then. Are you having this issue?
My 2017 gmc sierra had the same problem it would flicker and turn off and on, i fixed the issue but ever since that happened the driver side window doesn’t go down or up anymore… what could it be?
What all did you do to fix it?
Having issues with stabilibrak service. Cluster needles going wild & minor revving. Also “ reduced steering assist drive with care “ speed sensors were swapped out still having the issue do you think this may be the issue ? My thought was a faulty ground but no idea which. Hoping some one could be of help…
Ouu, that sounds tricky. If you're wanting to stay cheap try fixing grounds and see what that does for you. I wouldn't drive it after your tests but just to see what fixing those minor electrical issues solve (if any). Look up a lot of forms about your specific issue and see what they say, but if you're unaware of what to do I'd try a technician. I almost had to do it here recently, but I found an electrical issue with a voltmeter and my amp was faulty. Anyways, see what you can do DIY and if all else fails, technician.
I just solved this issue on my 2015 2500 Denali. The cruise control still randomly turns off when driving around right side curves. However, the issue you are experiencing are due to your stabilitrak sensor system. I replaced the hub on the bad wheel & it solved the issues. Your stabilitrak has roughly 8 different sensors connected to it. ABS, BCM, Wheels speed sensor, etc!
@@shortyd427 did you have any codes show up?
Had to remove that speaker for mine. The one under the wheel well I had to weld on the 10mm was stripped
Oof, no easy way out for ya
Thanks
Just the did the frame rail one on my 17 silverado. My ground was actually loose and covered in the frame wax. No idea how was even able to ground anything. Cleaned the frame to bare metal then tightened back down. No issues so far. My issue was stabilitrak and service trailer brake, and loss of power steering, and loss of power to guage cluster and radio all in one.
Lmk how this goes!
Thats what I'm going through now with my 18, although when I lost everything the radio kept on playing. The worst part is it would go in to reduced power mode and only idle untill I cleared the codes... on the side of the interstate. I fixed the problem for 5 months by replacing the SDGM module but now its back. The G218 grounds were perfect, the frame ground was just like yours. Hopefully it fixes the issue.. lately if it throws the codes I can't clear them as the scanner won't connect during that condition.. BCM module next or maybe somebody will steal this truck..
@@joshb124 Check your connections inside the distribution block (small black on top of your battery) to see if that is effecting you too. I cleaned the connections with some wire brushes and applied some dialectic grease on them before tightening down.
@@hunterrwiilsonissue came back with this week's snow event. Gonna try this ground point. Ugh
@@hummer3524 it’s definitely annoying. Hopefully cleaning and tightening these additional grounds will help
Theres another grounding point at the engine mount area on the same side and what i do is wire wheel the area change the ground wires then instead of using spraypaint I use whats called Cold Galvanizing Compound that sprays on just like paint but protects from the elements way better..
I didn't know about that galvanizing compound! (or back then) Noted for future reference, thanks Michael!
This happened to me a few time coming back from camping it said something about trailer brake system and it flickered off but the engine was still running and it turned back on in a sec. Any suggestions?
I’m not really too sure about that one. What do the Forms say online? I usually Google my issues and read the forms to see what others have done
Did you solve the problem?
Did you ever find the problem mines did that the steering was stuttering and everything
Unfortunately pulling insulation did not do anything to improve the grounding (dash). You have to get under the nut and clean contact to the body. Find out where that wire leads to and just run another body ground point wire.Thats a stupid place for GM to put a ground connection anyway.Check your pcm connections under the hood.
That stinks to hear. From what I’ve done it has worked, with all the sanding and fixing I did. What exactly are PCM connections?
My bad ground was behind the passenger side front tire, cleaned it seams to be ok now
This started up on my 2018 Silverado, the exact symptoms, Stabilitrak flashing, truck shutting off then right back on. Did the G218 fix, new negative battery cable, cleaned the contacts on the frame and engine block. Still doing it. Mechanic is telling me need a new battery, which is less than a year old. Different mechanic said change out the positive wire to the starter. Online forum says power steering issue could also cause this... about to just trade the truck in...
Did you give cleaning the distribution box connections a shot? It's the small box on top of the battery. I removed them, hit with a wire brush, applied diaelectric grease on there and tightened everything back nice and tight. I'd make sure all connections are solid, if you already haven't. But I hate to hear all of these issues. Makes a guy upset at GM for not doing anything about this :(
@hunterrwiilson I have not tried that! I am willing to do anything at this point to make the gremlin go away. I am die hard Chevy, like have the tattoo with VIN number of my 1995 Tahoe on my arm😁... what I would give for that truck back!
@@butters1877 yeah try it out! But that’s awesome! 😂 I miss the OG Sierra that started my love for trucks and kinda this channel, but I’ll get another, or that exact one, back one of these days
@butters1877
Update on your truck!
Thank you. I have a 2015 Silverado LT double cab that has the same symptoms. I took it in and they told me it was the aftermarket stereo. I checked the ground on driver side dash and it appears to have been cut already. Bolt was secured well but i took it off and kind of sanded it best i could. After i put it back on i cranked it down. I then moved over to the passenger side and cut the garnet around it off. It was also tight. I also took the bolt off the passenger side wheel well and grinded it down a little to make it smooth. Is there a way to tell of this worked or is it "try and see" kind of thing. At this point i don't want to have my kids in there until i can verify 100% its safe. Thoughts?
Sounds like you’ve done what’s needed. I’ve actually taken it a step further and cleaned up the grounds inside that “distribution” box that sits on top of the battery and then applied some dielectric grease to them. Haven’t had an issues since.
If you’re worried about putting your kids inside the truck, which is a very reasonable thing, I’d drive the truck around for a week or so with just you and see if it’s still messing up. Hope this helps!
@@hunterrwiilson So I actually cleaned the box the first go around and it looks good. I did notice my voltage was at 15.1 after consistent. I took it down a back Missouri road(pot holes and never repaired) and it didn't flicker or anything. I also noticed the rear speakers sounded more clear. Pretty sure that was it but time will tell. 3/7/2024. Ill check back in a month and let yall know. Thanks again.
@@dannyboykoch Sounds like you got it then! But yes be sure to let me and the others know! Blessings
Hopefully works mine did it to me on the freeway middle of the night was sketchy asf!
Everything alright with you and the truck?
@@hunterrwiilson so far everything is good did it all like how you showed and it seems to be running good hopefully thats all it needed thank you!
@@ahm.j1148 how’s the truck running now?
@@johnathanchacon2758 like new fixed my problems no longer turns off feel safe taking her out again!
@@hunterrwiilson my truck turned off on me again today while driving but that did help alot you think it just might be time for some new ground wires?
After fixing those 2 grounds as of now have you had it do the stuttering and shutting off again?
Not once
@@hunterrwiilson awesome thank you!🤙🏼
@@hunterrwiilson how are we looking 2 months later?
@@chriscastor2206 still going strong man. No issues with it
the neg battery cable has an excessive voltage drop when using the power steering(major electric motor) replace the neg cable and call it done. no need for the dash tsb
If, I hope not, this ever happens again I will be sure to use that method!
My cables melted where they run along the firewall near the exhaust manifold. Why did gm decide to run these grounds so close to the exhaust? It's an accident waiting to happen when someones truck just shuts off while driving without warning and you no longer have power steering or power brakes.
I know it's no fun at all. The fact that this video is approaching 100k views is concerning to me.
Man mine started having these problems after I changed the starter could it be any cables down there if not I will still check all my grounds , how do you know if the negative to the battery is bad ?
I would definitely check your grounds to the starter, but it could also be a coincidence 🤷🏼♂️. Electrical issues can be hard to track down and/or confusing. But something that I’ve done in addition to this video is I’ve opened up that box that sits on top of our batteries and disconnected the connections in it and cleaned them up as well. Then made sure they were super tight.
@@hunterrwiilson thanks man I’m gonna try this cause yesterday I was parked turned my a.c on and my rpms flunked and made the car shut off but all my lights work , currently doesn’t start at all
@@feardc2050 if the AC made the truck cut off, I’d go into the dash and go clean up the other side of the dash too. The opposite side of the one I did. That ground is allegedly for the AC, so that could be it.
Hey brother .....
I just saw your video and wonder...is you really solve that issue....I have the same problem...
Silverado 18....appreciate you reply thanks....
Have a good one!!!👍🙏
Sorry for the late reply, this has definitely resolved my issue, truck hasn’t done it since. Hope this helps!
@Hunter Wilson appreciated brother
I'll try it asap
Be good and bless
@@foox4ever132 no worries man! Glad to I can help! Also, try cleaning up some of the battery connecting points inside that small box on top of your actual battery. I took the top off, got some wire brushes and cleaned the connections there and then applied some dielectric grease to those points as well. Trying to maximize all electrical connectivity. Many blessings!
@Hunter Wilson
One more subscriber in on...thanks
@@foox4ever132 you’re the man! Appreciate you!
Thank you brother I will try this today I’ve been having the same issues for 7 months now.
Of course! Glad I can give any sort of insight! When you give it a shot let me know if it worked out for ya
The factory negative battery terminal was defective on mine. I crimped on a new one.
Smart move
When it cut off did you get a message telling you to roll your window up and down?
I’m not sure 100% sure but I think it may have. I remember something like that happening.
Mine did. My truck said something about Stabilatrack, two keys programmed and open then close driver’s window. Gonna try what’s in this video and hope it fixes the issue
Mine did say roll down my window and down 2017 Silverado gonna try this tomorrow
@@VvcrxzyV did this work?
@@Flaco20x mine does that
2014 Sierra 1500 with 142k miles - symptoms were "Roll down, then up drivers window" message and one click up on drivers window did not work - had to hold button up to get window up, voltage reading just under 14 when should be just above 14, gentle dash lights flickering, left turn had temporary loss of power steering, blinker use causes cruise control to kick off, clock suddenly 47 minutes behind and yesterday the truck quit and went black while preparing to enter main roadway. I disconnected negative battery terminal for two minutes, reconnected fired up just fine.
First I removed dash and cleared the rubber material from both ground posts G218 and G210 resistance codes - drivers side rubber was pinched under nut washer, just don't understand how assembler could do this at factory - the hole in the material means it goes AROUND the outside of the post, and they want a 40% raise in pay for a 32 hour work week. Started truck, still getting roll down then up window error message. Next removed, cleaned surface and ground wire end on passenger side inside wheel well, covered with heavy duty grease to prevent element deterioration. Opened hood and removed and cleaned ground post and end to firewall. Started truck, no more errors. So far so good. Prior errors included "Reduced engine speed" - code was wheel speed sensor - really GM, you're going to force me off the freeway because of a fricking wheel speed sensor issue? Update 10.17.23: Drove 600 miles today, no issues anymore.
It seems the electrical system and grounds on these year trucks Just didn’t come out good. I’ve learned to stay away from the 1st Gen of trucks. That’s where all the issues arise. But hope everything works out for you after these fixes!
Where is the "ground post and end to firewall" located?
@@drrexhuffman The front of the dashboard comes off, behind each speaker there is a grounding post. Then open the hood and locate the ground wire attached to the firewall on the drivers side. There are Utube videos showing how to get the dashboard off so you can get at the speakers, which I moved so I had easy access to the grounding posts.
Fixing the dash ground did nothing for mine. Haven’t tried the other one. Whole truck randomly shuts off. Gotta get rid of this thing or it’s gonna get me killed
I would try the other ground just to see. Some people have even replaced to main ground and that seemed to work. All up to you.
Did you fix it mine is giving problem too
Haven't had an issue since!
My 2017 GMC is doing this when parking or steering quickly at low speed, such as a u-turn. I will try this and see what happens. It is a nasty situation and am perplexed as to why GM did not protect these connections in a better way.
Definitely is not cool that not even a recall was considered
@@hunterrwiilson Yah man. America is really laggin now.
@@a-non1403 it issss what it issss
Did you end up getting the issue solved? Mine is going the same thing
So what ground connection do you think it was? You did both at the same time.
Having same issues with my 2017.
I've already done the ground under the dash, there's actually two, one behind each tweeter (take the tweeters out for easier wrench access) it solved a problem with the power steering shorting out, but lights and screens are still flickering, so I'm going for the frame ground tomorrow and will see how that goes
@@SlightlyStoopidGaming Just figured mine out.
It wasn't an issue with all 3 ground connections itself.
I cleaned all 3 grounds.
I did a cranking voltage drop test on my negative cable itself at the battery and got .700 amps.
It should be under .300.
Replaced the whole negative ground cable and it is fixed now.
The issue got worse as it got warmer out.
After I got the old cable out it showed no signs of wear or break in it.
BTW. The new cable showed .210 amps when cranking.
@@SlightlyStoopidGaming did it work im have the same issue
@@malmazan2124 it has lessened the issue, but I'm still getting the issue of the radio cutting out when I brake at low speed sometimes. Not as much, but it's still there. I think a full negative cable replacement may be the way to go at this point.
I replaced the battery and alternator. Solved the issue . Truck has good voltage
Good job tracking it! Not all electrical issues are the same so it's a good thing you found your issue.
@@hunterrwiilson i tried cleaning the grounds and doing the dash board thing too but none worked .
@@fukubish6024 anything is possible with electricals
Dude . This shit is so annoying thanks for the fix bro .
It was bro, you're welcome
So I've had the same issue as many on here - Usually starts with lights flickering, stabilitrack light coming on, and the steering getting hard, then the steering wheel jerks and all electrical power is lost. Usually this all happens during low speed turns such as pulling into a parking space. I fumble around for a few minutes, open the door, blah blah, and can usually restart in a few minutes. Anti-theft kicks in and tells me to lower and raise the driver side window. Frustrating as hell. After watching your video, I went after all the ground wires - The ones under the dash, the one at the block, the one behind the wheel, etc etc etc. Took them off, cleaned, scrubbed, you name it. I had hopes, and seemingly for a couple of weeks, it worked. Unfortunately, the issue came back. So now I'm thinking the common denominator is the cable itself. I could be wrong, but I'm nearing the end of my rope with this stupid issue. So, at some point in the near future, I will order a new cable, install it, and will report back after seeing if the issue returns after that.
Others have done the same with replacing the ground wire itself and it’s seemed to work for them, grounding/electrical issues are the worst since they’re all tied together and the possibilities are endless
This didn’t work on mine. Gonna replace the negative battery cable next before driving it off a cliff.
@@drrexhuffman make sure you get it on video if it don’t work, never seen ‘14 Sierra go off a cliff
Has it cut out since?
Not once.
Any issues after you cleaned the grounds?
Not one! Only cleaned the grounds inside that little box on top of the battery to ensure full conductivity!
My truck has shut off a few times on me like you said but I haven't fixed the issue
I haven't had any issues with it since the fix
I'll be trying it later on. Had my happen when doing it while on the highway. Very fun adventure
@@ecocav0222 Are you, and anyone with you, all good after it? Any damages to you or your truck?
@@hunterrwiilson No, just about a 4 second drive in complete silence from the truck. As I coasted with my butt clinched up. I really like the truck have had it since new in 2016. But I'm leaning on fence of getting rid of it. Although let's be real buying something else just means dealing with those issues of that vehicle. As almost every vehicle made in the two decades and now will have bugs. Basically pick your poison in the hopes it goes down well.
@@ecocav0222 Glad to hear everything is all well. But yeah, though getting rid of it would save you the trouble of dealing with a high mileage vehicle, you’ll still deal with any other nonsense with another. So you’re right. I just actually had to rebuild the transmission in this truck, definitely a hefty penny.
After doing this has anyone had the issue of their battery draining?
Sounds like you have a parasitic drain. Check some fuses for what may be drawing power.
I'll give this a shot. All my truck is doing is showing the "service power steering, drive with care" message. No other issues, no loss of p/s. Has a C0800:11 code. Going to look into these grounds!
Yeah it never hurts to try! Also, I'd look into your battery connections and see how stable they are.
Did this work for you?
My truck won’t go back together. I’m scared
So I’m taking that it worked for him ?
Yes
This secondary ground is not on the V6, at least I cant find it
Maybe a google forum can help
Almost died passing a car and switching into the oncoming lane and my truck completely shut off and came back on while going 50-60 mph. One of the scariest moments of my life
It’s no joke man, hope all is well currently. Get it fixed asap
Should be a recall
I've been looking for this comment as I haven't found common symptoms elsewhere.
When my truck does it (15 Sierra 5.3) it just shuts off, stabilitrak flashes and then the truck comes right back to life by itself.
I'm assuming this ground could be my issue?
@@shawngtpsvm it’s worth giving it a shot. My truck has yet to do it again since.
Mine does the same thing whenever I turn to the right...
Did that fix the problem? I just bought a 2015 high country and it did the same to me
It did fix it. Hasn't done it since.
Ok great I’m doing that tomorrow, I just bought the truck 2 days ago and was pulling in my driveway and same thing happened
@@lukedupuy35 I'd be pissed in all honesty 😂 but yeah it scared me at first cause my truck flickered at the end of my street and then just shut off as I backed into the driveway.
@@hunterrwiilson yeah man, so if doesn’t work for me im taking it back, but I hope it does bc I love the truck
@@lukedupuy35 You should have no worry, it should work for you.
Did this fixed the issues?
Yes!
Has anyone had the steering wheel lock up while experiencing this issue while still moving?
Yeah, since our power steering is electric it gets effected from this electrical issue
Wow, what’s the strategy to survive this if you’re going 60+ turning onto a off-ramp when it happens?
@@T5pinner Idk if you've read some of the comments but some of these folks had that happen. Thank the Lord they survived it and did what they needed to keep all parts together.
And GM REFUSES to acknowledge that a substantial problem exists!
Just gotta pick your poison with trucks nowadays 🤷🏼♂️🥲
Typical GM
TOYOTA.
2017 sierra having the same ducking issues almost died several times
Might be your keys are too heavy in the ignition
I did this to my ‘14 Silverado and was running good for 6 months till it completely shut off on me again, also my headlights flicker when I hit the brakes, anybody know any solutions to this problem?
Go check your secondary grounds. You know little box on top of your battery that has like three wires coming out of it? Open it up, unbolt those wires and get a rough wire brush and clean those connections, also the things that you just took off. I picked up some dielectric grease from O’Reillys and put it on those connections. Then tighten everything down very securely (without over tightening).
I had a similar situation where my power steering wasn’t working 100% and my whole truck was studdering as if a ground was sparking. Haven’t had any issues since. Hope this helps!
@@hunterrwiilsonI’m having this issue with my 2018 right now I randomly lost power steering on vacation….had to drive two hours with no power steering on 35s.
@@jatmomdadjt8744 ooooofa, yeah man give this a try and see if helps
What’s the update so far
Works like a dream!
Thank you I’m going to try this on my day off not driving it for now
@@ivanestrada2213 give it shot my man. Hope it works out!
Cut off the factory battery terminal connectors and replace them with the old school battery terminal connectors, both positive and negative. Problem solved. Those new fangled battery connectors GM put on the 2007-2014 batteries work loose due to vibration.
i think you got lucky, the ground bolted to the frame doesnt affect ignition components, you can unbolt it and the truck will still start up and run. And you technically didnt do anything with the ground under the speaker... good vid anyways !!
Flex head ratcheting wrench
Where’d you get yours?
Same happened to me when I come to a slow or stop and turn. Going to try this later. Last thing I want is this to happen in traffic
Exactly why I did this the next day. Definitely don’t want to risk that happening while I’m out and about
Update?
I have had zero issues with any flickering. This works!
this problem is dangerous, i almost got t-boned driving my wifes truck. this is a serious issue
Oh 100%. That’s why I fixed it immediately
Why didn't you start the truck to show us you fixed it....?
This issue functioned like a shortage, the truck would turn on just fine, but you never knew if and when it would cut off again. Sorry to not demonstrate but that is why.
Never heard it
T start
?
Mine was a weak battery
Anything is possible with electricals
This is why I moved to the south...this stuff is nasty
Didn't work for me... Now what ??? 🙄
Check your bonding and grounds inside that small black box on top of your battery. Open it up and disconnect those connections, clean them with a wire brush or so, put them back and use dielectric grease on them when tightening them back down.
I had to do this to my truck about 6 months ago cause it was being funny. Hasn’t had any electrical issues since!
@@hunterrwiilson Well. I tried it. Rest assured. I did the job right. Now it's worse than ever.... I'm at a total loss 😔. wtf
@@randymiller5008 :( sorry nothing seems to be working, it’s clear your electrical issue is more than just some grounds. Do what you gotta do, but thank you for at least trying some advice from a random guy on the interwebs! Blessings!
Thinking about adding a third ground wire off the battery. I've heard that works for some people. Idk
@@randymiller5008 doesn’t hurt to try!
I’m having this issue on our 2015 Tahoe, I cleaned the Frame mounted ground and the one on fire wall driver side, not sure how the speaker ground would become a problem?
It is called the p218 ground, not necessarily a speaker ground, lots of things go to it. The sound insulation begins to get stuck under the nut diminishing a proper ground connection at that point.
@@coltinwevley649 thanks for clearing that up, what a crappy place to install that,I’ll check it out
