one of my headlights come up but the other does not but if i crank it up when i hit the switch to shut them the both go the hell down corect me if im wrong but isnt there just a split from one light to the other so how the hell could this happen i cant have a bad conection if it goes down im baffled what could be the problem

 

The headlight motor bushing is probably bad. I think thirdgen ranch used to sell bushings for 10 bucks.

 

i recently rebuilt both motors and replaced everything with aluminum parts

 

Had the same problem last year, it was my bushings in the motors, changed them and now there perfect.

 

but i dont get voltage to put the motor up but i get it to put it down

 

You may need to replace the motor then. I did a search and found this thread about metal VS plastic bushings. Hope it helps

Wrong, Wrong, Wrong.....

The headlight door control module has separate circuits for each headlight, for this exact reason. If the control module went out, then both headlights wouldn't work. By having dual circuits, each headlight is separate & not likely that both circuits could fail at the same time. This way, you at least have 1 headlight & don't lose both.

 

I didn't know that. Thanks I learned something new today!

 

well were is the controlmodual for the pas side headlamp so i can fix the dam thing

 

It is just 1 Module, with dual circuits inside it.

On the firewall, drivers side, just right of center & left of the brake booster. It has 1 plugs on it & slides to the right to come out of its bracket.

 

So thats what thing does! Im not being a smart***, as sad it sounds I did not know that. Even worse, Ive had at least 8 Firebirds in the last 14 years. I feel like an idiot.

 

so there are no splices in the front of the car to be problematic right? where would i find a new control unit too?

 

If the headlights come up with the ****, that indicates the motors are good (and you rebuilt them anyways), so that points to the motor simply not getting power.

I bet you could jumper power to the motor. If it goes up, that points even more towards the Module being bad. Maybe the 2 headlight plugs could be switched on the Module & see if the one not going up switches?

 

ok i fixed the modual took it apart and murdered it with conact cleaner and it started to work again thanks.

 

i know how you feel ive had that thing out when doing master cylender service and a few other times who would of thought. The dam thing almost looks like a small ECU type of thing

 

Glad it worked out for you. I had one doing the same thing & cleaning it didn't help, so I replaced it with a spare I had laying around. At least I didn't hafta buy one.
