Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
I have had this problem before. You need to make sure the switch is locked on the tie bar(rod that the pedal assy goes thru) and make sure it in place on the pedal, then depress pedal and hold at the same time pull back on the switch to set it in place.
Then have you checked for power and ground? Have you made sure your switch is not defective?
