My 89 Silverado is experiencing problems with the factory cruise control. The cruise will no longer maintain the set speed - speed slowly drops off after setting the cruise. The accelerate function does not work any more. It feels like the servo is still partially working as when you touch the brake or turn the cruise off, the truck decelerates noticably as it normally would when the cruise is deactivated.
I did a little looking on the auto parts sites on the internet but didn't see anything like the servo unit I have in my truck. Frankly, I don't know if it is the servo unit anyway...
Any and all help appreciated,
Thanks in advance,
Gurbax
