i have a 95 grandprix,the doors lock and lock again when the brakes are pressed
Check the wiring near the brake pedal. Perhaps the pedal is rubbing some wires and causing a short. Does this only happen when the car is in "park" and you depress the brake to shift? If so it may be a problem with the shift/ brake interlock device. This is a solenoid, usually located on the steering column, that is de-energized when the brake pedal is depressed, allowing you to shift out of "park". Check the wiring for that too. The solenoid is usually on top of the steering column so you'll have to lower the column to inspect the wiring. Not hard. Once you remove the lower steering column trim panel there's 2 nuts. One on each side of the column. Remove them and the column will drop. HTH. -Jim
