Ok, Who Knows This?

[BlackBirdDaddy]

Now, when I turn on my marker lights the headlight doors pop open which they have never done prior to today. WTH?


Then when I turn off the marker lamps, the doors close and then the left door motor is screaming for help for about 5 seconds and then stops. Could the gear be trashed?


Any help would be appreciated.

they do weird things like that when a gear is stripped.

It sounds like the gear is sripped, I wonder if there is bcm personalization for how the light doors are commanded ?

Thanks, I'm going to rip it apart today between firework blasts.

I've heard many times, the best replacement is a brass gear set. Good luck!

Turn both lights on and disconnect the arm from the motor to headlight on the side that grinds. Spin the motor by the splined shaft 180 degrees. The 360 deg gear only uses 180 degrees of motion. WHen you rotate it to the other side youre using the new untouched side. Saves time and money. I did this last year.

I definitely dont miss messing with those stupid headlight motors.

My headlight doors have always gone up when you turn the marker lights on. I just assumed it was supposed to be like that. Lol.

Mine used ti do it too. On all 3 or my trans ams, my 91, 95 and 96

I would always turn my markers on and manually put the lights down.(had a drill
With me at all times for a quick down)

I replaced the gear with another plastic type (Dorman) from Autozone on Friday. The headlamp doors worked properly (stayed closed with marker lights on) until Saturday. Then the plastic gear broke a tooth again. Today, I had ordered a couple of brass gears to eliminate the possibility of failure again!
