I just purchased this car and the cruise control works sporadically at best. When it does engage, it never fails though. I continues to work, accel, decel, and everything else. It getting it to set that is the problem. I tested the steering wheel switch with an electronic engineer and determined the problem was somewhere else in the system. In adition to any advice from anyone who may know how to fix it, wheres the best place i can find a cheap or even free electronic schematic of the cruise control. I want to fix it myself.

 

theres a certain minimal speed that it would engage cruise control

please explain how does cruise control DOESNT work - what happens
