Need HELP with 1967 RS Headlights

We have put new in new motors and wiring harness for the hideaway
headlights. The passenger side headlight will open....the driver side will not. Has anyone had this problem before and could offer some tips on what to look for to get this corrected?? Thanks

check for power and ground for the motor, test the motor with direct current to make sure it isnt a faulty unit, then check to make sure youre getting a signal from the switch, without having schematics of the system, im not sure what else to tell ya.

Does anyone have a schematic for a 1967 Camaro RS headlight motor system or do you know where I can get one? The right hand door will open but will not close. The left motor is burned out. Any suggestions? Thanks CamaroRS
