I recently bought my first f-body a 2000 ws6 t/a. Since I had it the headlights have not worked properly. At first I thought that (re)connecting the wiring harness to the motors and replacing the gears would fix it. Tried that same thing. Replaced the headlight module TWICE! Didn't help then one side would go up and not the other checked all connections and they are good fuses are good too. Replaced drl module and still the same except now on low beam all.four lights come on with a brownish glow they're not burned out though I checked. Then on high beam one side (same side that goes up and down) will work correctly. Now I've pulled the bcm out to check it out. Can someone please help??!! Im going insane thanks in advance!

sounds like a ground issue more than anything or a possible short. might try to trace the wires and look for a place they might of gotten melted or something.

also have you tried replacing the actual headlight switch?

That I haven't tried but as far as headlights coming on they come on just not with the correct amperage I think

May be corrosion on the motor connectors. Can you post pics of the insides?

I don't have them removed at the moment. They were kinda dirty but I checked that they were working whenever I replaced the gears.

Mine were working fine until I unplugged them to do a gear swap - and then this stuff started happening. I had to take the male terminals out of the connector body and polish them with steel wool and also had to replace some female terminals that were too far gone. Once I cleaned them up - all has been perfect.

A big problem with them is a ground issue as stated above.

That may be but if both circuits are good going into the motor. Wouldn't it mean that it's not receiving power from the source? It could be ground but it could also be that its not getting the correct signal. Then the bcm is too blame because all the other modules are good.

You can test this at the motor connector. I believe the ground wire also goes through the connector.

You can forget about the BCM - it has nothing to do with the headlights in any way.

Normally when you have multiple bulbs that illuminate improperly (tail lights, head lights, or whatever) it is because of a bad ground. What happens is that the power to one bulb ends up grounding through the other so both illuminate rather dimly.

The headlight doors and the headlight bulbs are also completely separate except that they are controlled by the same switch. However, the headlamp door control module shares a ground point with the left headlights so that's the first place I'd look.

Alright I will most definitely look into that. Where exactly is the ground? Left fender well?

Located all four underhood grounds cleaned them and retightened still have the problem

Its only one side that's jacked up, right? If so, I'll be the problem is in the headlight door motor connector. (All the door motor wires and bulb wires go through that connection.) Got to unplug it and check it out. You can test the ground continuity at that point, etc.

The headlight grounds are on each side of the rad support frame.

I think I have found my problem. The connectors were corroded as **** and burnt to hell. Thanks a lot guys appreciate it!!!

Yea... that's ugly. I had one like that and was able to remove the terminals from the connector body and polish them up a bit. Getting the corrosion off the plastic may require a bath in something. If you are adventurous and want to rebuild the connectors, crimp on new terminals, etc. I can assist with part number references.

You found the problem. I cut off the harness and made my own connections.

Thanks for the offer wwssix99 but I ordered new motors with harnesses and new connectors this should fix it I hope

One of those connectors is going to stay in the car. You need to get rid of all that blue and white junk. Will the male connector stay in the car? (I don't remember.) If so, that one is really easy to clean up.
