MY firebird headlight motors do not work. The lights turn on and off, but motors do not go up/down. I replaced the headlight switch with a spare I had to no avail. Is there some sort of fuse or relay that may be bad, or is it most likely a bad ground wire? BTW, it occured when I popped the headlights up accidentally while driving, and when I tried to make them go down w/ the switch, nothing happened.

So, since both sides are affected, I am assuming the motors are fine but there must be a bad ground or relay or something. Where are the grounds for the lights located (BTW car is '87 firebird), and how do I trace this kinda stuff?

Thanks for any and all help...

Well since it is a 87 there is no relays. Just a module. Check all fuses and then make sure the motors are not seeing any power. THen check the module, it is located abouve the brake booster. Look for the red wire, and yellow wire. Make sure the red has 12v all the time, then check the yellow wire for 12v when the lights are on. I think that there is a white wire, if im not mistakein there should be 12v when the light switch is off. (I might have the white/yellow wires switched around). If all is good then the module is bad. Otherwise you have a wiring problem.

Do the motors have a specific fuse in the fuse box, b/c I couldn't find one when I checked? I'll have to go through it again I guess...
