Car Forum / Pontiac / Pontiac Fiero / May 200785GT cruise control problem
My cruise control works fine with the following exception which has cropped up on this years frist outing. Cruise is not disengaged completely when putting on the brake and releasing. With cruise engaged (and cruising) as long as the brake is held down a little the car will coast (no throttle) but as soon as the brake is released the car wants to resume speed (throttle back on) as long as the speed is above appx 25mph. The only way to stop the car from moving is to turn off the cruise switch on the column (or hold the brake down till 10-15mph). Any ideas - worked fine last fall (stored since) 85GT v6, Automatic, Loaded with all options, 13,000 original miles, stored it's entire life, never driven in the rain or on gravel road, everything on car is original except engine oil. Thanks in advance for any ideas. Michigan The clue is that there isn't (87SE man) an automatically resume-when-brake-released option. Braking or clutch disengages the cruise completely. Since turning the main cruise switch off shuts off the cruise there is little reason to believe the speed control is defective or that the actuation is at fault. There are two switches on the brake pedal. (At least on an 87 SE) One switch lights the brake lamps. The other disengages the cruise control. It is likely the cruise switch is mis-adjusted or broken. I'd check the schematic to see whether with the brake off if it is normally open or normally closed. They are sort of self adjusting in that they have ratchets. The switch is placed to be too far out and the pedal causes the ratchet to push the switch back. I've had some similar problem with the clutch starter cutout switch, a problem you won't have. Mine is usually fixed by pushing the switch back to where it belongs. Dave S. > My cruise control works fine with the following exception which has cropped > up on this years frist outing.
