cruise control
OK guys, my wifes '95 850 Turbo has had a intermitent cruise control problem. It would work most of the time, but shut off at random, reset and good to go.
Someties it wouldnt set at all.
Now it just wont work. Where is the cruise control module under the hood? Is it vacum ran? Is maybe the cruise computer bad? Maybe the brake pedal switch?
Any ideas?

RE: cruise control
Thank you, no problem on the PDF. I will check the throotle cable and then the vacum line at the brake pedal.
I was messing with the EGR and PCV the day before it died completly. The EGR valve is bad so i was looking to see if I could remove and clean it. I may have messd with one of the throttle cables I suppose.

Spike,
The vacuum that operates this is not at the throttle cables, it moves the actual throttle pedal itself. In addition it is a vaccum pump not engine vacuum (Would work backwards when you got boost). My guess is it is electrical. The intermittant problems you mentioned are most likely not vacuum or mechanical. If these modules are anything like those in 94'+ Volkswagens then it is not surprising if the module is bad.

RE: cruise control
It should be infront of the pedal but I believe above the brake light switch. Look for a switch that has a vacuum line going to it.
My Yellow one does the same thing but evertime I check things out all seems fine. But also sometimes I need to pull back on the brake pedal for it to work.

RE: cruise control
So after throwing my back out crawling under the dash I still cannot see a damn thig. I see the brake pedal, the bar that goes through the firewall into the engine bay to the master cylinder, I see part of the brake light switch, but nothing else.
The bottom of the dash covers everything. It is very well built and neatly pout together, I am pleased with that, but man, what a pain in the rump to try and fix.
We will have to take it in to get fixed once we have the money I guess.
Thanks for all the help guys.

I really wrenched it a couple of weeks ago moving furniture in the house and it was feeling better, then I layed on the foot well flat on my back to look under the dash and when I went to get up I couldnt hardly move.
At least it is a long weekend and I can recover before Tuesday. lol. It sucks getting older.

RE: cruise control
Do youanyone you can borrow a hand vacuum pump from?
Or you might be able to rent one from a local parts store.
This way you could 100% rule out a vacuum problem.
I used to have the diagram on how to remove the relay and jump with wires to activate the pump motor but I cannot find it or I would have posted it for you.
