when the car is started the headlights pop up and the headlights and foglamps come on. after about 30 seconds they shut off on their own.... any ideas?

i believe the issue started happening after the headlight gears were replaced.

edit: car is a 2001 c5 coupe w/ automatic tranny

 

Can't see as where replacing the gears would cause that. Has something to do with the body control module. If I can remember and have time, I will check wiring diagram for your car and post. [8D]

 

yea, so i figured it out today..... it would only happen when the car was started in the garage.

turns out the "twilight" option was turned on... [sm=lame.gif]

 

Glad u figured out. Old saying in auto repair business -- KISS-- Keep it simple stupid. LOL
