Here are some Volvo cruise control fixes to work through if the cruise control on your Volvo stops working.

So getting the cruise control working is the next big item on my list for my 850, especially as the weather starts to warm up again and I start thinking of some longer trips I’d like to take.
I’ve had the car for about 7 months and the cruise control has never worked. The left stem on the steering wheel works for signaling, but the sliding switch and rocker switch that control the CC don’t do anything. Is the stem the likely issue or is there somewhere else I should be looking?
“The stem could be the problem. On my S70, I took it apart and found a broken wire. After soldering the two ends together and shrink wrapping the connection, all was good.
However, this is not usually the point that is the problem. Here are a couple of other common Volvo cruise control fixes to consider:
Usually, it’s a broken hose on the cruise control pump that resides under the battery tray; or

The stop/brake light switch that is associated with the brake pedal has broken.
I checked both of these places out first before finally taking my turn signal stalk out and apart. Good luck and let us know how things go.”

I wanted to throw my 2 cents in as well. I had this very same problem.
Ultimately it was the brake switch that prevented cruise control on my 94 850 as well. But for some reason, some idiot had reversed the vacuum lines on the pump so instead of creating a vacuum, it was pumping air into the valve for the gas. So i switched those out and all works good.
Download the manual and it tells you how to diagnose the problem. It is great! I love reading those pages and learning as much as I can about my Volvo!

V70 manual 2005 estate . Cruise control info on dash bord comes on only at standstill or when in gear with clutch pressed down. When driving on motorway cruise control does not engage and nothing showing on dash bord …….please help ,,,,,!
Yes, to replace stem, you have to remove steering wheel. It is suprisingly easy though. I recently bought a new stem and swapped it out in about half an hour. Unfortunately, this did not resolve my issue. I’ve also looked at hoses near the vacuum pump because its a common failure point due to battery acid eating up hoses.
Everything looks fine. Next I need to check the brake kill switch and/or verify the pump is working well (not sure how to do this though!)
HI All,
Newbie. I replaced the under hood cruise control relay, under driver’s side brake switch, and vacuum switch, with salvage yard parts. Still no change, cruise control not working.
To check stem do I have to remove steering wheel?
Thanks in advance
