This dude literally shows up whenever I have to "google" a question. Good job at being a volvo diy machine.
Thanks for watching.
Robert does it again! My 1998 V70 (non-AWD, 190k miles) cruise control quit about seven years ago. Brake switch, check. Accelerator linkage arm, check. Vacuum hose near battery, sliced! I reconnected the ends using a piece of windshield washer hose. Cruise control, works! Wish I had known about this when it quit a long time ago
+padepede lol, thanks for watching.
A huge thank you from France Robert. I managed to get my cruise control back up and running simply by pulling back up on the brake pedal. No doubt a garage would have found some other reason and charged a fortune. Thank you so much :)
Sad but true. Glad you figured it out.
Holy shit Robert. You are a life saver. Glued a little washer on the brake switch after diagnosing it how you showed, and it worked fine again. I’m on my third Volvo and have saved SOOO much money repairing them myself with the help of your channel. I don’t know if I can ever buy another type of vehicle again. Can’t thank you enough.
You are welcome.
This is why Robert's show and tell videos are the 100x better that a read about it only forum post! Thanks.
+VictorSinclair Good deal, thanks for watching.
This video helped me solve a long time annoying behavior of the CC dropping 5 mph before accelerating to the set speed. From what you showed, even though you didn't mention it, I noticed that there was an adjuster screw above the throttle pedal by the linkage to the bellows. I adjusted that until I found the sweet spot so that idle is not increased but when I hit cruise set the slack is out of the cable and the Bellow can react faster. Now only 1-2 mph drop before speed is back on target and if I hold throttle steady for half a second, no drop at all! Big thanks.
+VictorSinclair Very good info, thanks for sharing.
Robert you’re a godsend for working on old Volvos, hats off to you sir
thanks for your support.
Just posting to express my gratitude to you for this video. Was preparing to troubleshoot a non-operating issue with the CC on my 98 V70 GLT. Your tip about the vacuum line to the pump under the battery tray was spot on. The short length of rubber tubing that attaches to the pump had corroded. A quick fix for me because I already had such tubing from servicing my 87 Volvo 245 which has 419k+ miles on it at present and is still going strong. I'm cruising easy now fully operational. Many thanks.
And thank YOU for being a Volvo repair legend. I can’t tell you how many of your videos have helped me get my 96 glt wagon whipped into shape, 240k miles under its belt and hopefully at least another 240k to go.
Glad to help
Robert, one of the reasons I have now bought a -96 850 is your DIY videos. Always loved the car, but your videos enables me to carry out some possibly expensive repair jobs myself. Thanks & respect.
Cool, glad to read you can do some of the repairs yourself. Hope it takes you many many miles.
I have a 19 9870 Volvo and your guidance has helped me figure out how to run my vehicle. Thanks for taking the time to make these!
you are welcome.
Robert. By following your videos I was able to fix the Cruise Control on my 98 V70xc. It was a broken vacuum line just under the battery tray, a trouble spot you had mentioned. Total cost 97cents and an hour of my time. You rock buddy!
kim davis Very nice.
Crystal Clear Explanation.
I'm planning of buying a Honda City. I was apprehensive of opting cruise control, in view of potential problems. But after watching your demo I feel confident in facing them if, God forbid, they ever should come up.
Most usually don't.
Huge thank you man!! My cruise control just stopped working and I couldn't figure out what was wrong. But you just helped me big time. My problem was the number two, the link to the gas pedal had popped out. So simple to fix! I have a V70 - 97 and can now cruise again! Thank you again!
Nice, thanks for watching.
Hi Robert, thank your for this great video. My cruise control was not working any more, after I calibrated my brake switch in spring.
I checked it again this morning and saw the link to the gas pedal had popped out.
Now I was searching for a picture how the links are in right Position, found it in your video! Juist coming back from a test ride, works as new.
Thanks from northern germany. My Volvo 850 20V 1995 Station and me are really happy to have you and your site
+camicatzelg very nice. Thanks for watching.
Took at look at the cruise control on my Volvo 960 a year ago and couldnt figure it out. This video made me take a 2nd look. Sure enough... one of those vacuum lines had a huge crack in it. Good to go now!
Awesome!
Thank! One of the very few remaining issues on my 95 850. Looking into it again since my turn signal lever just decided to snap.. Preciate the good flow of info on these solid autos!
Hope you get it fixed.
thanks again, Robert. After replacing my battery cable I didn't have cruise control for my 760 mile ride to NYC and boy was my knee hurting. After watching this video, I realized that I forgot to reattach the vacuum hose to the air handler. I haven't tried it yet but I'm sure that it will be back to gliding down the highway sans foot pedal. Cheers.
Ouch! I can't imagine driving without cruise for 100 miles. LOL
So I reattached the vacuum hose, checked the foot brake switch n still no cruise. I'm checking on gas pedal ball joint next then on to the fuses. Holy moly, didn't think it would be so hard to get it working again. My right knee is killing me. Heehee
Lol, wow again I couldn't find anything on the speedometer. Mine isn't working. And I just was being watching your amazing videos and work. When you said the speed sensor was bad, I was like bingo. Lol I was worried I would have to pull the dashboard and cluster. Then put a new cluster in. Or tear the cluster apart to figure it out. Could still be a wire or plug. Maybe something else. But I have a feeling it is the speed sensor. Thanks again for all your time and help Robert.
What kind of car do you have?
Nice, they just started working all the sudden? That's nuts.
Good. Hope you find the problem. Thanks for watching.
You are welcome. Thanks for watching.
Thanks for this video !
I have a 2001 xc70 with 645000km on it. It is in very good shape but the worst issue is that the cruise control is flakey.
I will inspect the hoses, linkages and switches as you explained here.
My battery is in the trunk though (I have the wagon model), so I guess my cruise control vacuum pump is not under there ?
When I go to work in the morning, it usually works fine, but at random moments it will just disengage. Sometimes I can set it again and then it works just fine. Other times it will not re-engage for miles. Sometime the entire system will disable (as indicated in the cluster) and will not turn on again. However I can fix that on the go by going to neutral, turning off the car and then re-starting. I once put it in reverse at highway speed because I went too far while putting it in neutral, not good !
Could be a problem in the ABS system or instrument cluster. Brake pedal switch would be your best bet.
From model year 99 the cruise control on C/S/V70 (P80) is totally electronic, no vacuum hoses and such.
And this applies to all Volvo's with an electronic throttle body, so also all P2 cars.
In most cases a malfunctioning cruise control on those cars are because of a faulty stalk or a problem with the ABS system. Also electronic stability control failures will make the cruise control malfunction.
Thankyou for your video! I have a 2003 C70 convertible but they are based on the 850 platform so I'm hoping I can sort this at the weekend with your advice
thanks for watching.
you know i have to see how good my cruise works my girl loves to speed in it. . by the way the lights on the numbers on the radio you fixed for me are lighting up now lol i did the climate control lights to now to do the switch lights lol
hi Rob checked fuse bad and arm off peddle good. no luck. checked pump totaled replaced no luck. sucked on pump. line open vacuum. Took long evap line from tank ran it to the front seat where I sucked on it again leaking at break switch took both off parts car and it seems clutch and break are different one is 1 in longer they had the wrong one installed works perfect thanks me and you all day every day lol
glens falls NY lol
Nice, I love cruise.
Hy Robert, thanks so much.
You are welcome
The minus button on my cruise control doesn't work, but everything else seems to.
* I see this is answered below, change the stalk.
Thanks Robert.
Thanks for watching
Hey Robert, thanks for the video! On mine, it's clearly the vacuum tube next to the battery, just like you said. How do I go about replacing it? Is there a specific size vacuum tube that I can get at the auto parts store and cut to fit? Also, where does the other end of that tube go? Do I need to replace the whole thing, or is it common to just replace a section?
Joel Crane I just got some vacuum line and spliced mine together, cutting away any part of the tube that was damaged.
this is her husband. with this good info i will be able to fix my cc on 98 v70xc (great car). works great if you know how to and do all service and work yourself. another test you can do is to create a vacuum with mouth with the rubber hose coming off the vacuum motor under batt tray and see if cable at the throttle body moves, no vac troubles if cable moves. sure i will be able to trouble shot additional points as described in video. thanks.
Thanks for the tip and thanks for watching.
Hi Robert, first thank you for all your videos. They cover a lot of useful things :)
I have one question, is it possible to install a cruise control set to a car which doesn't have one? I didn't find much about this topic.
Hi Robert, thanks for giving me some hope! My cc (V70 classic) does completely nothing. I already checked the brake switch... Now I know about the accelerator pedal connection, where the vacuum hose is located, and the relais and cc module... Things to do this week, I let you know 😊 thanks a lot! #subscribed
Edit: I can also check the cc handle 🤭🤭🤭
Do you have any ABS issues?
@@RobertDIY yes, sometimes the ABS light is on (sorry for my funny English)
That will kill the cruise on your vehicle.
@@RobertDIY hmm ok... Then I think that is the case... 😯
Okay i will do that. Thank you again
Hi Robbert. My CC works, but poorly. When I set my CC, it does’nt work directly, after 10 sec I feel my gaspedal being pulled. Also speeding up/down with the +\- control doesn’t respond quickly. Is it a vaccuum leak?
Probably. What kind of car do you have?
I have a '98 V70
Love your videos.
Thanks for watching
Thank you Robert for another great video. My 1998 V70 XC's problem is maintaining the speed once cruise is set, especially once it encounters even a small incline. On perfectly flat ground it seems to mostly work. Do you have any recommendations before I dig in? Perhaps a small vacuum leak would cause this?
+Patrick Litwin yes
I’m troubleshooting the cruise control in my 1980 240.
Please explain the 10 second rule for setting the cruise? I’m assuming it also applies to the 240 model?
I'm sure a 1980 system is different.
Just to clarify the brake switch topic, there are two switches, the bottom one with the white plunger is the brake light switch, the cruise control switch is hidden above that and is all black with a two wire plug and vacuum release line attached to it. one of the retainer clips on this switch was broken on my car so it was loose. The pump and vacuum lines held and vacuum would release when pressing the brake (using the relay bypass test), but the plunger switch was not in deep enough to close the electrical relay, so the cruise could never be set...until I taped the two switches together to help hold the cruise control switch in place, and added some shim material to the brake lever to ensure the relay closed with the brake released. Call me cheap but I have a hard time spending $40 to fix a problem caused by a broken plastic retainer tab, they should have went a little heavier on the switch mounting design...
thanks for sharing.
Good morning Robert. The cruise on my '98 V70 does not slow down when you push the minus switch. I am guessing that the contacts are worn, not making a connection and the whole cruise switch stalk needs replaced? Was hoping you could offer some insight on that before I start taking things apart. Thank you Robert, your videos are quite helpful.
+Jeff Schmidt that would be my guess. About a 10 minute job.
Great video! Thank you for your help! Rgs CJ
CJ Carl Johan Thore Good deal, thank you for watching.
hello, i have a 94 T5R and the cruise is intermitant. somtimes it will engage sometimes not. also it will hunt, not noticeable on the speedo but i can tell from my turbo gauge thats its accelerating a bit then decelerating constantly, even on the flat.
Is the ABS light on the dash lit? Could be a small vacuum leak, could be a bad speed control relay, sadly I have not narrowed those cruise issues down to a fast fix yet.
@@RobertDIY i have had some ABS issues in the past with calliper over heat codes, but they seem to have gone recently and i put them down to ABS ecu connector or ABS pcb probs. the only other prob is the tracs/abs light will come on often because of the brake pedal position switch on the master cylinder needing me to fix its pcb but im scared if i remove it it will not seal well afterwards and Volvo dont sell them. i will have a look at the relay as apart from maybe some play in the pedal actuator i cant think what else would cause it.
thanks for replaying.
Robert, I have a 1993 850. It has a linkage with an elbow joint and an adjustment nut that limits its extension. I am guessing it is the pulling stress on the linkage, that creates a vacuum in the bellows that makes the CC work. What is the significance of the adjustment nut and how do I know its adjusted properly? I also have an open T piece on the vacuum pipe. Is that correct?
+stefis6 probably. I am not sure about the adjustment issue.
Hi Robert, love your videos...I have a 2000 S80 and a mechanic replaced my serpentine belt and pulley. I don't use my cruise and radio often, but a few weeks later I noticed that both my radio and cruise have no power and don't work...any thoughts?
+Karen Turner Not really, check the fuses.
Thanks did that so I guess I need to take it in...ugh!
Hello is it possible to install a boardcomputer in to a 850 sedan? The car is of 1995
Hello, Robert! I am wondering how I can install the cruise control (from a donor car) on a volvo 850 that has never had it installed before. Do I need to replace the ECU?
I don't know and I don't think the ECU matters.
Hi Robert, great video as always, i would love you to do a install video.
+Simon Hammond I think all 850's in the US have cruise.
Most of the 850's in the UK cruise control were optional, i.e my ' 93 850 SE had cruise control yet my current '96 850 S doesn't. Thanks anyway. by the way my 850 was from the UK T.V show Gavin & Stacey series 3 driven by James Corden.
+Simon Hammond cool. Do you have any documentation to that?
Yes, the V5C (pink slip) has the TV company as the last owner. Also search P26LLU.
If your blinkers don't work, your cruise won't either. Your key may not be releasing after starting. Tap the key backwards very slightly. Love my Volvo.
Thanks for sharing
Does the brake and clutch sensors need to be fully pressed in when your foot is off the pedal? My sensors go only half way in when pedals are not pressed. Still need to check the hose near the battery but I guess I am dealing with these sensors as my cruise sometimes (very rarely) works.
I don't even know what kind of car you have???
Robert DIY oh sorry man, forgot to mention. 850 manual is the car in question. 😊
Thanks Robert...
+Antonio Batalha Thank you for watching.
Hello! I have a small little curious question. Does your cruise control go back on if you allreay have set it, on lets say 50 mph and you then gose back under 22mph an clicks in the resume switch, or will it just be able to resume if you are over 22mph? Thanks!
yes
@@RobertDIY Is that a yes as it works or not or that all my hypothesis was correct? Thanks
Hi Robert,
I admire your DIY videos, they have helped and saved me a lot of money since january 2012 when I bought my Volvo 850 N/A 144BHP sedan 2.5 litres MY 1996.
I have a question regarding my cruise control which by former was installed wrong. The linkage arm on the gaspedal was “in front” instead of the back of the gaspedal. I managed to pull it out of the gaspedal without breaking the old fragile plastic. My question to you is, would you write or better make a video where you show, how the adjustment plastic screw works and how it should be positioned? I’ve been googling around and haven’t found any post about this issue. Best regards from Tom/Denmark.
I don't know how to do that. You may need to consult a repair manual.
Robert DIY l
Robert DIY Thanks for your answer, I’ll try to optain the installation guide for Cruise control, maybe it will answer my questions ;-)
Robert I love your Volvo vids and I am going to subscribe. Question. I have a 2004 s60 that is giving me po573 code which is brake switch circuit high. Not real sure what this means. Should I try that brake switch behind the brake pedal as in your video here? Thx man you are awesome
+joegolden481 are all of the bulbs working properly?
as far as i know. could that be why my cruise does not work?
Absolutely.
Hi , can I check switch brake u case cruiser control not working Volvo S80. 2008. Diesel 2.0 ?
th-cam.com/video/cWKOi8D4SWQ/w-d-xo.html
Hello Robert, are you still here? Question..my 850 t5 had starting problems which turned out to be the fuel pump relay (found out thanks to your video). I had a mechanic who tried to start the car and after several tries the engine was working for a while (this was before I told him to try to bypass the fuel pump relay cause the problem wasn't solved yet). Now what happened next was scary, all of a sudden my gas pedal went full throttle out of it self. The mechanic eventually disconnected a vacuum pump from the gas pedal for preventing this happens again. Now when I hit my brake pedal I hear that pump hissing. Do you know what can causes the cruise control go haywire? It's so strange that this occured at the same time I got this fuel relay problem..the only thing I can think of is that while removing the fuel pump relay I touched the cruise control relay.
No, is the throttle Body spring broken?
@@RobertDIY thanks for answering. Haven't checked yet but don't think so, as long as that vacuum servo is disconnected the problem is gone besides the hissing sound when I hit the brake. In this video of yours it shows what happened to the gas pedal but with the engine running. (The cruise control switch was off btw) th-cam.com/video/2KiESwZ7PTk/w-d-xo.html
Hi Robert! I bought 1997 850 gle. Many things were solved with your comments! Finally the cc had an open vac in the clutch pedal! Now I still have an abs warning and no movement in the odometer. Do u have any idea why ? Any way u can see the speed traveling.
Best!
If you have an ABS issue the module is probably bad.
th-cam.com/video/0zV8nGeGukQ/w-d-xo.html
Thank you for prompt response!! Wanted to let you know we are fans of you!!
So from argentina, best wishes!!
As from the volvo is a 97 850 gle with 77000 kms, so it’s new!! That’s why I still think there’s any other thing than abs module.
Will keep you updated!!
Best!
Martin
OK
hey Robert first off love the vidios I bought a 1994 850 for three hundred dallors. it runs great but as you know I have ask you a few times on some ideams . I was following the video found the hose for the cxruse control to under battery but the you don't show where that hose went to can you show me where that ends up in engine the person that had this Volvo sure didn't have a good manto work on it that's why it was so cheap car runs great but for some long time love ,I had a ford truck before this car I can do anything on the truck
james j halliwell You just have to follow the tubes. They are usually damaged under the battery trey.
Is it possible to retrofit cruise control from a junk car if my 850 doesn't have it?
I'm sure it is. Especially if it's pretty wired.
Hi Robert. Have a 99 V70 Turbo and was having trouble with the cruse as well. At the same time the engine was acting sluggish. Did find a hose to an electrical connection not fully seated but still the same symptoms. Most hoses look cracked and slightly dry rotted but are still OK. Tried and tried to locate the cruse modual and pump but can not. Not under battery or air cleaner and not near the throttle body? Now this is an all electric throttle. Looked under dash but nothing comes close and no linkage to accelerator. Any other places I can look? Now the good news in all my efforts to remove MAF, battery, air cleaner and was about to clean throttle body I reassembled and it runs great including the cruse. I think by disconnecting battery it reset everything, think that what it was?
Cracked hoses are not OK, you may not see a break. Probably the ABS module.
Robert; Any ideas as to where to look for the cruse modual and pump?
hey robert my 1998 volvo s70 the spedo dosent work and the cruise controll either its like the same time they both failed could you help me?
th-cam.com/video/0zV8nGeGukQ/w-d-xo.html
My volvo v70 98 doesnt have cruise control so i wanna upgrade it. Is it simple or is much harder ? What i need to do? Just upgrade Handle from other who has cruise control or complete set?
Bring it by so I can check to see if it has the other 12 parts needed to work.
@@RobertDIY ok,ty bro
Robert, I've got an odd problem: the + and OFF button work, the Resume and - button don't work. I figured it had to be weary buttons. But: I changed the indicator and the problem is the same with the other indicator. Any ideas?
Maybe a problem with the relay.
@@RobertDIY I tried to figure this out but another odd thing appears: I do have cruise control, but do not have the 101/102 relay that you are showing in your other video. Fuse box looks the same but I just have an empty space there. Maybe a mod on the last v70I models? Where should I look?
Manual is not helpfull either
Hi Robert, firstly thank you for all these videos you did, they are priceless.Then I want to ask you a question. I have some problems with my S70 2.0 T5 AT. My cruise control does not work. I checked most of the things. Vacuum pump, hoses, brake pedal sensor are OK as far as we can see with my mechanic. When we diagnose the cruise control via OBD, we get the code 122 speed sensor. There is nothing wrong with my odometer. I think I have the problem you had that you mentioned at the end of your video, but I couldn't get how to check or fix it. Can you please explain more detailed? Thank you again.
What year is your car?
+Robert DIY 1998
Does your ABS & Tracks light bulbs work? Do you have either of those warnings?
+Robert DIY I just solved that problem by pinching a piece of plastic between module socket and pump. I have no more abs&tracks light and they work fine.
I do not recommend stressing the ABS system with a wedge. You should consider having the module replaced or repaired.
Can the cruise control work if my ABS module is faulty (abs and tracks light on - getting this fixed)? Cuz if it can't I'm just gonna wait to see if repairing the ABS module solves it. Cheers. (v70 20v 1997)
No.
@@RobertDIY thanks for your promt reply Robert. I wont bother with the cuise until the abs is fixed then. ;)
@@RobertDIY Ok. Fixed the abs module. Still no cruise control. Brake switch seems fine and and pump arm too. Should I change the relay? V70 98
gramoukdoom gramouk did you find a solution?
Hi Robert. I have a 1999 v70 xc. The cruise control works for a while but then shuts off and won't work again until I have turned off and restarted the car. As if something has over heated maybe? Have you ever had a fault like this and have you any ideas? I only seem to have issues with it over long journeys otherwise it seems to be ok
Probably something to do with the ETM or ABS system. Have you scanned the system with vida?
@@RobertDIY no but it has had a brand new genuine throttle body not too long ago. It does have an emission fault too it says catalyst below efficiency. The cat is non genuine as I can't find an OEM. And I've checked everything else. But when it went for MOT they did say it had a throttle body code in it.
wiring to the throttle body is a known issue for these cars.
@@RobertDIY ok I'll try to have a look at that thanks for your help. Great channel 👍
I've also found broken wires on the MAF that caused issues.
Hello Robert. I think i have the problem with the CC in my 1993 volvo 850, the wiring problem in the cluster, since i have installed the board computer. Before when i only have the tempeture and the clock, the CC works perfect. Mayby i have stretched one of the connections in the cluster?? How do i troubleshoot that? Thank you.
What cluster do you have? The Yazki or VDO? I believe the trip odometer was designed for the VDO cluster.
Robert DIY
Yes its the VDO i bellieve, since the board computer fits right in, and working properly.
When I had my issue, I had to replace the wire harness at the top of the cluster. The latger of the two.
Robert DIY
Okay, i fear that was the solution. Do yo think it is a plug n play job, or do i have to cut and reconnect the wires manually? Thank you for your answers.
I had to splice the wires together one at a time. I used phone line splicers.
Thanks for the video. Going to diag my car.
hey in volvo V70 when you set cruise, in instrument cluster no light indicates cruise is on this is normal ? cruise works fine but no light.. this is my first volvo..
+Deivis Bass what year is the car?
1998
hi robert! i got a 850 from 1996 and the cruise control doesn't work. how can i test that relais?
It only has one relay. Is the ABS working?
@@RobertDIY hmm good question. I don't know at the moment cause we didn't use it . But what do I need to do if it doesn't work??
If the ABS is not working, you will see an ABS light on the dash.
@@RobertDIY the ABS light is off
@@RobertDIY so what do I need to check now?
Hey mine work it just shuts down after a while of running it !
+kevin dahlr there is a problem somewhere.
i fix my cruise control by moving the brake svitch.. and then i fixed the sterio.. and now the control dosent work.. what to do?
Its a Volvo s70 tdi 1998 mod
Maybe the switch is bad.
the vacum hose had slipped of the intake, so i put it back and secured it, and i change another brokend hose. it works like it should now 😁 thanks for all your videos😄 your Awesome!
You are welcome.
yes yes yes very nuts lol lights up great lol
First off, thank you for all your volvo vids. Great help. Your awesome! Thought I would add that the wire in the stem on my s70 volvo was broke and was exhibiting the symptoms of intermittent on off, like hit a bump in the road and it would turn off. Soldered them back together, taped them and good to go.
