i have a parts car that had working headlight motors. I took the motors, the control module, the headlight switch, and the harness of green and gray wires that connects everything.

I put all of that (it was from a 1990 firebird) into my 1988 firebird and it still doesnt work.

One time i noticed that about 5 min after i had turned the lights off one of the lights had gone down. That only happened one time.
