Rearview Mirror 02 S80 T6
 

My reearview mirror has a seatbelt light and autodim feature that is not working. I don't see any buttons on the mirror to turn it on nor is the mirror getting any power. Is there a fuse I could check for this or is it going to be a wiring problem.

I forget if there is a fuse for it or not.
The Mirror is actually a computer.

Does the central locking work?
Does the remotes work?
Does the sunroof work?

Try locking and unlocking the car with the key and see if it works then.

The unlock and lock works both in car and with keyless entry. And the sunroof works as well....

Then it might be a fault from the Mirror.

If those functions work the Mirror has power to it.

You might want to have the Dealer pull codes.

When you say pull codes....does that pertain to any warning lights? Such as check engine or service soon lights? Cause I have no warning lights of any kind.

The rear veiw mirror is not connected to any lights but the system holds codes.
The proper name for the Mirror module is a Upper Electronic Module.

I popped my Fusebox open and it was missing two Fuses, replaced them both and now it works. Thanks for the info Tech!
