Cruise uncontrolling

Recommended Posts

I have a 1999 C2 6 speed with a cruise problem. Basically, the green light comes on with the switch at the end of the control stalk as normal, but the cruise will only work for about 1-2 minutes after starting the car. After that time the speed slowly drops off until the cruise is not working at all. Even if I turn it off and on, or reset it, the cruise will not start to work again until after the car has been shut off for a while (like over night).

A work order from the mechanic of a previous owner says "the cruise works while the generator is disconnected". Is this possibly a grounding issue or???

All input would be appreciated.

I fixed my cruise, It was a wear contact inside the brake switch, It send positive to the module,I opened the switch, cleaned It. Fixed!

Thanks for the input. I checked all electrical connections and the cruise now works. I can't be sure, but I think it was the main plug connection into the cruise unit was not making proper contact.
