Thanks Jamie!! This fix walked me through my problem and corrected it, no mechanic needed.......no money needed. You rock.
5 years after this video got posted and this information is still GOLD. The fuse method worked instantly. This should be the first thing anyone tries. I did notice it still doesn't want to shift around when use the switch so I'm guessing the module is bad because the motor seems to be working fine. I finally got rid of that whining noise. I think mine was stuck in between shifting from 4w high and 2w high hence the whining noise. I though I was gonna shred my transfer case but this fixed it Thank you so much!
I CANNOT EXPRESS TO YOU HOW GRATEFUL I AM THAT YOU POSTED THIS VIDEO!!! I had the transmission replaced in my Chevy Trail Blazer and when I went to pick it up, they told me that the service 4wd light was on because the transfer case was not communicating with the transmission. And they also told me that you CAN DRIVE THE VEHICLE LIKE THIS.... So we drug it home and started searching youtube for a solution that we could do ourselves. And we found you...GOD BLESS YOU MAN!!!Keep those videos coming....I will be forever grateful that I found this video.....
+Rebecca Murphy ok you just made the Car Man's top ten list , lol , this is exactly why I do this thank you for your support
Thanks for the post. I've been looking all over the web for answers about my 4WD problems I've had with my '03 HUMMER H2. This by far answered all the questions. Really, thanks!
Thank you for your time and your care to help people out that are in need!!! Personally, I greatly appreciate it!!!! God bless you and your family!!!
Hey car guy! Just wanted to say thanks for the helpful information that you so happily shared. I have a 2007 chevy trailblazer ls and i unfortunately came across a problem with the 4wd low... Couldn't get it out of gear. I followed the steps in removing the encoder and manually shifted it out of 4low to 2hi. Lifesaver! Need a new encoder (motor wasnt responding to its commands.) But thank you for the help and continue the helpful tips and then some. 🤘
Direct, spatially descriptive, concise and with caveats included - awesome, man! (liked)
I got 99 problems and now thanks to you Jamie, only 98. Thank you! Just had to disconnect battery for a while and reconnect. $0. You rock.
Thanks man I appreciate your help im going to tell my dad about this he's a mechanic and now he can help me do this 😁
Thanks Jamie!! I followed your's and a couple other videos (I compiled them). My truck is a 2005 GMC Silverado1500.
Here is the compiled procedure I used.
After I took the ground to the battery off for 30 Minutes and re-installed the ground, I took out two fuses (Treck - 30amp and 4ws - 15A) briefly, and put them back in. Then I went into the cab and turned the truck on (but not start). I put the truck in (N) ---not park---. I then held the 2w and 4wd low switches simultanously until the red N light on the 4wd panel lit. Then I pressed 2wd. I heard a loud clunk and no more stuck in 2wd.
This is the lead up event:
I was going up a hill with some loose rocks and I selected auto 4wd and heard a load clunk. At the top of the small grade. I stopped and put it in 2wd and it made a "gear grinding sound" from the left front tire. I tried switching to 4wd and all hell broke loose. So I figured the front left wheel got stuck partly in drive, because in 2wd a gear grinding sound came from left front only.
Thanks Jamie. Your's was the missing key in the other videos. I owe you dinner :)
Almost a decade later and you’re still helping people. I had this same problem today and the fuse method worked like a charm. Doing the Lords work brother. I appreciate ya
Thank you! Glad to hear that the video is still helping people. It’s stories like this that make me want to keep them going.
This worked like a charm. I have a 2006 Chevy Tahoe z71. I took the first step from his advice of disconnecting the Bat cable and the removing the fuse. Waiting about 30 secs. and plugged in the fuse again and reconnected the bat cable. Cracked the truck and initially it didn't work but place in Neutral, hit 2wd. It engaged roughly with a loud sound and worked like a charm. I still have the "service 4wd" on the DIC indicator. Which means I will probably have to replace the encoder motor sensor or the transfer case motor soon, if the problem persists. Thank you for posting!!!
+Scott Richardson that's awesome brother I'm glad it worked out for you and if we could do anything for you in the future please let us know
Thanks Jamie , Looked this up to help a friend out. Your a good person posting things just to help others. Many of God's blessings to you.

Jamie You are the man! I have a 2004 Isuzu Ascender which is basically a Trail Blazer. I was stuck in 4wd low for the 1st time ever. Undid the battery cable for 30 min. unplugged that fuse and voila! All working again! Hopefully I will be good to go now, but if this happens again I feel totally equipped to take your additional steps to go further! Really incredible advice saved me a bunch! Greatly appreciated! Massive thumbs up!
great video, am personally aware of the nomenclature,but for those that aren't, it must be a huge help! and I watched it to brush up on it, big help!.thanks!
Thanks a lot man you was the last one I watched last night and I went out this morning and I got 2 Wheel Dr. and got to work on time.. I have always been good with a wrench but when it comes to the electronic i am lost in some ways it seems easy and then others it's not thanks for the info,, Rick Tanner Lake Ozark Missouri,,,, if you ever have any boat dock or boatlift questions look me up
Thanks a bunch. I've been looking for a while on how to fix my 4wd. I figured it was something that I can do myself but didn't know exactly what to look for. U r the man.
garnet basarath thks yeah the dealers just try to make it so expensive and complicated in reality it's really inexpensive and pretty simple to do, good luck man if I can help you in any way shape or form let me know
@@jamiejonesthecarman how about where the tcm motor thingy is so I can remove it? 2009 gmc sierra.
Brother you saved me a big headache with 0 dollars spent i flashed the TCM and it woke it back up I'm glad I had subscribed to you before I needed help with this issue. Thanks again !!!!!
THANKS!!!! Been stuck in 4wd low for 3 days. I can't wait to go outside and get to it on my 06 TB
Same dude wtf
Thanks for the info! This helped me solve my issue. My 05 Silverado was stuck in 2 HI but then got stuck in AUTO 4WD when I kept trying to engage 4x4. I trouble shot it down to the shift motor/encoder assembly. The new one came in the neutral position but couldn’t get my transfer case to go into neutral position. Watched this video about putting the transmission in neutral first and just like that, I was able to rotate my transfer case into neutral and the new shift motor lined up perfectly!
did you turn the splines by hand or did you use vice grips or something? I want to do this but I do not want to use vice grips on my splines I do not want to damage them
thank you!! I needed your specific video to show me how to get the module out...yours was the best.
thankyou, like the cat channel
Thanks a lot for the video! My wife’s 2004 Bravada was stuck in Awd and after watching your video I was able to get it in RWD by removing the actuator and turning the transfer case counter clockwise. New subscriber !
How many times do you have to turn it
Thank you for posting this!!! You've saved me.
so glad i saw this video...literally step for step this is what i did with the exception of tccm....only if i had seen this sooner i would have went straight for the module...but again thanks
It will not go into 2wd . Clicks twice that's all . Now what ?
You sir are awesome!!! This saved my life today!!
Thanks! I found your video too late, as I took it to the dealer stuck in 4 hi. Needed dang truck ASAP. $907 bill for new motor. If I’d known, I’d have done this and delayed repair. Only $200 on Rock Auto.
I got my trailblazer 02 stuck on 4 lo nd you saved my day 👍🏽 thank u
Hi Jamie thank you so much you made my day after a year looking for the TCCM and over 15 videos on u tube I finally found it thanks to your video
Emile Nicolas Hi Emile, no problem at all. So glad to hear that the video helped you out. If you ever have any questions or need help with your car just let me know.
Sitting in the truck with my husband... thank you!! 2 high :)
Thanks brother you're a lifesaver!
I have an 02 Yukon and apreciate your advice and simple fixes, you save me alot of money and worry. Thank much
Larry Willis Jr i also have an 02 yukon with the same problem. what did you do to fix it?
Most helpful video I've ever watched my blazer got stuck in neutral the transfer case that is the vehicle I haven't yet had on the road but had this horrible grinding couldn't figure out where it was coming from rear brakes rear end front drive shaft transfer case was have stuck in between
Jonathan Maynard Glad to hear that you found the video helpful man and that you were able to locate your particular problem. Hope to see you on the channel often and if you have a moment, take a look at our contest video. Its our way of doing a little something to thank you guys for making this channel a success.
Hey man ,I'm the guy you helped. All I need and want is 2h. And I was stuck in 4l
Being a residential service provider i go to my my money😅
Thanks for the video. It help I am stuck in 4wd hi and auto I just pull the 8 fuse and I hear a motor run and it goes into 2wd.. Any thoughts what to replace
Thank you! Worked for my 2015 Silverado 1500. Unhook battery. Drain for 30 mintues. Re hook and pull the number 6 fuse and put the fuse back in and now my transfer case shifts just fine!
Same here
Yes. On the 2014 and 2015 Silverado and Denali 1500 it is fuse #6 rather than #8. Identified as "4WD Transfer Case Electronic Control Fuse".
Did you unhook the number 6 fuse before or after unhooking and re hooking the battery?

Great video. Well presented and fun to watch. Thank you.
Thank you so much. Super informative, learned a lot and you saved my ass brother. Really appreciate your time and effort to help us financially unblessed . Exit me- a wiser man.
thanks for the info. I'll be saving myself some money today! ps.. cool sound effects car man
Great help. I don’t think I’ve ever seen a car repair video be so to-the-point with no fat around the edges. Probably the easiest TH-cam repair i’ve ever done. Shoutout to this guy
What are you talking about? It was 2 minutes before he got to anything I could have started there
What? Dude acted like he gets paid by the word.
@@ShortArmOfGod most of these videos should be like 30 seconds
Thank you very much the first option you said to try worked like a charm!!
The fuse reset worked on my 2016 Silverado (for now) as well. Thank you!
Hey, how did you know what fuse to pull ?

Worked on my 2015 Chevy. #6 fuse for the win!
You saved me big $$$$ and some of my already thinning hair....THANK YOU YOUNG FELLA!!!
Jamie, you are the reason why Americans are the greatest people on earth!! Thank you for simple common sense explanations!
Thank you so much! Very glad to hear that it helped you out.
Thanks for posting. Had to put bosses 2012 Chevy 2500 in 4x4 to get unstuck today. It wouldn’t go back into 2wh. Had to pull over and take actuator off the transfer case and manually shift it. Will diagnose the issue later but feel like it’s the tccm.
thanks a lot for your help very well explain very helpful I just drove 15 miles in four wheel drive low at 35 mph pulling my boat to get home but I would do this in the morning thanks again
great video helpful ,retakes aren't always bad it's real time not rehearsed
Pulling the battery cable and fuse did the trick. Thank you brother!
I hv an 04 Tahoe and idk which fuse to pull. What is it labeled as??
Thanks for sharing your knowledge.. I have the 04 Envoy I both last year and haven't had this problem I had last night till now. So I was going down the street on a slick snow filled road and I turned the dial to 4L, and it lit up the spot. But when I turned it back to L2 and that light stayed on the 4L so I flipped it back and noticed it had some play where the doal went past the 4L and back to 2L but that light stayed on. So when I got somewhere I could shut the truck off and back on it then let up the L1 where I keep it. So what's that used for where it turns with that extra play past the 4L setting
Are you just talking about the switch
Well, I was able to take the encoder motor out and manually put it in 2wd without having to take the driveshaft out. It did work. Thanks for you time, your information and help.
Yeww thank you so much mate helped me out as well have work in a couple of days and this just helped me out bloody legend give this guy a raise 🙌🤙🏿
Thanks ole bud ,from one country boy to another I appreciate it
Not sure if it was your advice or luck but I couldn't find a wrench to disconnect my battery so all I did was remove the spark plug and waited a few minutes and it worked thanks very much!
Huge Thanks to you! I just disconnected the battery and reset the fuse like you said and it worked like charm!!
Did the battery pull and removed and put the fuse back in. 02 trailblazer. Worked like a charm. Thanks for the video!

Thank you for that video that help me get my car moving again drove to my buddy's house to ride to work car was fine got back from work went to Aleve and it was in and it like the brakes were on why I was trying to leave and turn around but thank u again
No problem man!! Glad that the video helped you and thanks for the support.
Hey Jamie, Just want to let you know this video helped me with my 2006 Porsche Cayenne S. Has the same set up did what you said to get it out of 4 wheel drive low and the problem went away. Thanks for your info. There isn't much in the way of "four wheel drive system fault" on the internet when it comes to Porsches. The Cayenne has a similar transfer case, transfer case module and transfer case motor. Saved me lots of bucks. Thanks again SteveKJR
THIS GUY IS AWESOME!!!!
Your the MAN ...... thanks 🙏
hey man cool video my 04 chevy trailblazer is being slughish when i start off from red light or stop sign but after second gear it drives fine any ideas on what it might be?
Hi Jamie, You saved me a lot of time and money, the reboot fixed the problem. you're the best...
Amazing county boy. can you tell me about fan clutch had it changed runs rough he went from smooth to a gas hog?
Very informative video, as are others you have uploaded. I reviewed all comments/questions but did not find an answer about the system in Bravado/Rainer. Is there a neutral position for this one speed transfer case? It looks just like the two speed. I want to be able to tow on all fours or will I need to install the transfer case found in Trailblazer/Envoy? Thanks & keep up the good work.
FYI I have '04 Rainier with front axels already removed, not interested in having anything but 2wd & neutral.
Great video and a big help. I will be watching more from Jamie
UPDATE: I Got the truck back in working order! Thanks JAMIE for the video, I couldnt have did it without it, I was able to find which FUSE to pull to do the reset as you explained , it is "TREC" fuse lower right corner 30amp in a 4 fuse group with radio fuse in it, for you guys wondering which fuse in 03-06 GMC Sierra or Silverado... so FYI, I must have defected my encoder when I tried to operate it without installing it, when I was trying to get spline to line up to reinstall it after transfer case swap.I got a used encoder at parts yard for $15.00 (HELL YEAH to UPULL YARDS!) I used my module and not the one I got at the yard, didnt seem same because the GM P/N was different so I didnt want to chance trying it and not matching, even though was same M30/NP8 vehicle. LESSON to learn here is DO NOT attemp to operate an ENCODER without having it mounted, I read on another site that there is a WARNING of this on a BRAND NEW encoder.
Hey! My '03 TB (bought in 2014) felt stuck in 4H for no reason 2 days ago. The clock had also reset. Weird. In trying to figure out WTF I learned that the xfer switch is supposed to have lights -- it never has since I've owned it! Found your video, and this good ol' *girl* fixed it with your help. Thank you!!!
+Jackie Sullivan that's awesome go have some fun in the mud
JamieJones TheCarMan Minnesota. Snow. Ugh. But...I drove the first snowy roads of the season today - used A4 and it handled great. Sure wish I'd known about the switch light earlier! I also think finding this issue was a happy accident and the "feeling" I had of being stuck in 4WD was due to low tire pressure. ✌
+Jackie Sullivan you sure are right about Minnesota being cold is the coldest place I've ever been in my life
You ROCK, Jamie!!! Thank very much for your help!
Sanya Vanya No problem at all. Glad to hear that the video helped you.
@@jamiejonesthecarman Hey Jamie, ive 03 Suburban1500 5.3 votec my 4x4 shifter motor gear is at about 7o clock position,T.Case spline is @ straight down 6 o'clock. WHAT POSITION ON T.C. SPLINE IS 2H? i know you mentioned 2 counter clock wise,while on,but felt a some grinding as i was beginning to turn.
I just replaced RMSeal but was unable to return 4x4 shifter(on transfer case) to its fitting,original position gear-spline..think it needed to be in Neutral when removed. Truck hasnt moved since
1. Shifter still off, can truck drive 2H w/o it?
2.can drive train be put in another position that would cause truck not to move??
I also put on new(auto salvage) shift cable...had a bit of grinding shifting from drive-Park - ground when passing "R". that drive train installed in wrong position? Any advice appreciated.
Great response carman, or not. FYI there are some AWD models such as the 2002 Bravada, Buick rainier and Saab 97x. I tried a TCCM from a trailblazer and it gave me 5 codes for things the AWD does not have. This means interchanging TCCMs is not so simple.
This is a very good video . Wish all of em were this good My only question is was that shaft stem shown in the two wheel drive position? Thanks
Thank you!! My battery went dead and I replaced it. My 99 blazer was stuck in 4 lo, I had not pushed the button.. I purchased this Blazer some time ago, thought that most kinks were worked out of it. I have done a lot of research and kept a record of what I found. Checked and there was your link.
disconnected power supply to fuse panel under the hood. Turned on light switch and went and did some thing else. Also pulled two fuses. Later came back and connected fuse panel. Light switch was off. installed two fuses. Got in car and put gear selector in neutral. Noise came from under car and lights indicated that I was in two wheel drive. Test drove and I was. Thank you so much.
I don't understand how you can turn the lights on with the battery unhooked
Awesome man!! Thank you very much!!
I just got a 99 and trying out after I got home its stuck in 4hi. It'll go to 4Lo and back to 4Hi but nothing when I press the 2Hi button. Mine has 3 buttons and not a twist switch. Is there a way to simply put a cable on the spline and just pull and push from inside the cab? I have several heavy built cables for like engagement of the PTO for truck dump bed. Personally I love the simplicity of anything manual over all the push button and all the sensors and servos.
i never tried that but i bet you can , , share if you do it
Ok, this was one of the most helpful vids I have seen. BRAVO!!
Your advice worked on my vehicle and saved my butt in a pinch!
Question..
I have a '96 gmc Yukon that is is NOT engaging the front Diff. I replaced the front actuator and it still wont engage. 4x4 low/hi blinks, however when letting the actuator hang and press the button...it doesn't engage outside the vehicle. You can hear a 'clunk' in the torque converter when button is pushed. I drive in a river to get to the property, did something get wet?
Help?
+SkylordGaming have you tried to reset it, it does seem like an electrical problem based on that its blinking which is telling me that there is a problem in the electrical system, is it possible to take it to the dealership to get a scan
useful info. Thorough explanation. Dope sound effects! 👍👍
Excellent presentation!!
awesome video brother, thanks!
thank u so much my man much love from pa
Thanks for the vid it's a big help
I have a 2016 escalade and I pulled fuse #6 and it worked for me. Thanks for the feedback. Different fuse # but same methodology. I did not disconnect the battery either. I'm out of town this saved my ass
Hi we are out of town with a 2016 Escalade and are stuck in 4 high. Wanted to see how long you left fuse #6 out for until it worked? Did you do anything else? Thanks so much! We are 7 hours away and really need to get home!
About 10 min
You should be able to do the speed limit in 4 hi
Dude You Are The Man!!!!!
Fantastic video!!! Great information and to the point and no blah blah blah - Great Job sir!
it worked just like you said unplug battery & fuse Got live action God bless you.
Awesome great job
I have a '04 Tahoe. Idk which fuse to pull. Anyone know which one???
i saw a post that said my encoder ring is why it tells my to service 4x4 . light says it s in 4x4 hi but im sure it s in 2 hi . any thoughts ? will the puter make it shift into another range as im driving ? can it be driven with the shift motor off ?
Great video JJ CarMan!! That is exactly what my mechanic said over the phone, however my 2001 Silverado 1500 HD LS is stuck in neutral I think, I just bought it, did full tune up and drove fine for 100 miles then I got to a stop sign and no gears??? I can hear a spinning sound when I try to put into drive but no gears, thoughts?
To bad you didn't have mechanics shop here in Evans Colo thank you jamie
JamieJones TheCarMan , I have a 2008 Silverado and I'm having exact problem you are describing. Brother its awesome how you come on here and help so many people. I think your awesome. Anyway, I did all you said , have the battery terminals off and now waiting..I'll get back to you. My truck sticks in either 2 wheel or 4 high...How long can you drive in 4WD. It's late May here and getting pretty warm, like 20 celcius..Thanks again brother
cool let me know if it works or not
4w drive working GREAT..Wish I had a way to thank you..I spent an hour reading foolishness until I read your's...What you were saying was what I was thinking , well sort of...Thank you sir, truly appreciated!!
Did u pull any fuses??
Great video and it is nice to see that you respond to questions. My 2002 Envoy battery went dead. Now my 4wd service light is on and my car will not go into any 4wd setting. My 4wd has gone out before and it cost me 350. to have fixed. Not sure really what they did but it sounds like they just replaced the module. Could it be possible that it needs to be replaced again?
+Rose Dumonthave you tried to reset it like I do in the video cause I gotta feeling its just in sleep mode
Disconnect the battery for an hour. Reconnected and back to good. Can’t thank you enough. May God continue to bless you and your family!
So you did not have to remove the fuse also? I'm not sure which fuse it is mine are a little different than his were
Hey Jamie You are awesome. Thanks
+Lou LaFountain cool glad it helps you
Do I have to disconnect the battery to install the tccm or can I do it only with the ignition switch in the off position?
MrAzul73
Always disconnect the battery when changing a control module. It's a computer, you wouldn't unplug the power supply from the motherboard in your computer while it was powered on would you?
Very informative. In my case mine is locked up in 2wd. Do I still turn the spline counterclockwise? Or clockwise?
It does work in 4wd but as you know, vehicles in 4wd don't like turning sharp so would sure love to get it back to 2wd.
Good video! Thank you!
Replaced the switch, didn't work. Got a "new" TCCM from parts yard. From a 2004.....bam, worked. Didn't flash or anything. Did not kill power, just replaced and hoped for luck. Jamie is right though, the 2002 model is notorious for this, so do not replace with 2002.....there are multiple crossmatches for this part.
Thanks Jamie
+Terry Christle right on right on my brother glad it worked out for you
What model/make are you using for the demo? I have a 2007 Chevy Silverado and the #8 fuse trick does not work. What does the #8 fuse control on your demo model? Thanks.
Thank you. This is the exact problem I'm having
OK I think this is the video that will solve my problem with my 03 trailblazer! (praying)
I have already replaced my switch and transfer case actuator last winter. It will go into 4hi for maybe 15 mins but then shifts into 4 low automatically somehow like after i park it or try to shift to 2 hi again when parked.
Good job on the video...Thanks much
You seriously help me !!!
Thank you man, I just pulled the fuse and it went back to normal!
I have a 2007 silverado classic and paid a person to work on it. It's fixed 4wd working all is fine for now. The person I paid to work on it got another person from another shop to work on it that specializes more in the electrical department but I was told there was some kind of short that was happening that was actually burning and ruining the transfer case motor and more then one motor was tried before the problem was pinpointed. So all's good now and imma try and focus on some other things that I need to correct on this truck because having no 4wd and all that starting making me care less for the truck but that will change now i'm just glad I was able to have a person local near me take care of it. I Should had done this a long time ago though.
Jamie. I am having a problem with my 04 Chevy Silverado. It's stuck in 4low. I tried replacing the shift indicator. That didn't work. What are the chances it's the module or the shift motor?
Andrea Worthington Hi Andrea, more than likely, its probably the shift motor. Be sure to let us know what you find out.
