Before I go fuse hunting, does the auto dim on the mirror share the same fuse as the sunroof?

 

Auto dim? Am I missing something?

 

The Cobalts don't have a Auto Dimming mirror. Unless a aftermarket one was added like I did in mine.

 

Only 2005-2006 Cobalts that have OnStar have auto dimming rear view mirrors.

 

Bump

 

Well instead of waiting a week for someone to help you with a pretty rare question, why not start poking around and help the next person out?

Used some logic and educated guesses, I'd start looking for the OnStar fuse.

 

I would look if I had a factory one.
My aftermarket one I used a fuse tap for the sunroof fuse.

 

I did, I've been pulling fuses and replacing them and I still can't figure it out.

I don't exactly have tons of time either, so I can't tinker with it for hours on end.

 

Your S ROOF Fuse 15a also says mirror with UE1. That might be the one your looking for.
