no theres definitely a module that does it. with bad gears they always pop up with arm/disarm of the car. its really annoying/embarrassing.

It still shouldn't happen. Its possible the stripped gear causes the module to become damaged through to much power flowing through it. logically it shouldn't happen but.. its GM. Electrical Gremlins are their forte.

popping up when the switch is put to the middle shows the gear is good enough to operate, its more a switch problem from what i see. It incorrectly supplies power to the wire controlling the motor relays, closing then and causing the headlights to rise.
Changing the gear will do nothing to alleviate a bad switch. It will fix the one headlights problem of grinding but do nothing to fix both rising on the middle switch position.

I had it happen to both headlamp motors on my old V6, if one goes the other probably wont be to far behind. I still don't see how the OP was more concerned the lights popped up when he turned on the parking lights than when it emitted the grinding sound.
Big Chuk, is there a lug nut missing in your avatar?

That fixed the problem with the "grinding" & the buckets coming up with the park lights![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
Unfortunately I bought the "new" motor from O'Reillys "20 miles away"
because it was closest, spent about an hour or so putting it on in the rain, then after working them a few time to be sure it was all lined up right........
the motor froze up. To be continued....stay tuned for part 2. By the way the other side is now working properly.

not trying to flame but what you say is wrong do a search...."The headlights on the Trans Am/Formula/Firebird measures amperage (resistence) to know when the headlight is fully up and fully down (controlled by the BCM). When a plastic gear in the headlight motor gets stripped, the system keeps powering the motors and thats why you hear a jackhammer/grinding type noise coming from the headlight motor when you lock/unlock the doors or when you turn on/off the headlights or even your parking lights.""Danny2tek"

I am having the same problem except with a little twist. The twist is that the Driver's side parking light is on and the passenger parking light is off when the light switch is in the Off position. When I turn the switch 2 the Parking Light Position the headlights flip up and the Passenger side Parking light comes on. So I know it is not the bulb. Does anyone think this has something to do with the headlight motor ? Also jus noticed the passenger side of the 3rd brakelight is also out. ( Going to get a new bulb and check that out 2morrow.)

I am getting the grinding noise from the passenger side when the light flips down and when alarm is armed. So I was thinkn it was the headlight motor as discussed in this thread but I am not understanding the parking light.

Yeah me either. Called the Chevy dealership and they had no clue on the Grinding and tried to tell me to bring it in so they could look at it and charge me $70 jus 2 look at it. I told them the grinding was from a bad motor and they told me sounded like a Grounding issue. If anyone has any insight let me know. I am going to go ahead and get a new motor and change that out 1st.
