Hi all, 2000 c5, my drivers headlight occasionally will not popup until I cycle it 2 or 3 times. I don't hear any grinding so I don't think it's the gears. The light goes on even if it doesn't popup. Any suggestions would be helpful. Thanks.....Lance

 

I had the same thing and it turned out ot be the gears. Don't be fooled by the lack of a grinding noise. In the end I replaced both motrs through FRED BEANS for half the price of GM

 

I have the exact same problem with my right headlight on 2000 coupe. I know the gear is not bad because I took the cover off and found the brass gear is fine, the rubber piece in there is torn a little but don't know if that has anything to do with the problem. I just saw this for the left headlight in another post. It is specifically for the left and not the right but don't see why it would not be applicable.

Here is a TSB that came out quite a while ago that fixed my problem very similar to what you describe. Seems to be almost exclusive to the 2000 yr model. Replacing the insulator tips on the mounting bracket travel stop tabs works like a champ. The TSB has a diagram illustrating the fix.

hey Velvet Glove.

You were right. The gear finally started making that awful ratcheting noise. I ordered Rodney's brass gear rebuild kit for $50 and rebuilt the motor. Easy job and saved me a ton.

Thanks,
Lance
