I'm thinking it's the mirror or some part of it, not a sensor. After all, the temp and compass info surely come from two different sources. Does the auto-dimming still work?

I'm not sure if the auto dimming is working or not. I'll have to check that when I get home. My thought was the mirror as well. I'll probably have to have the dealer check it. Thanks for the help.

I'd be checking the power to the mirror..........

I gotta ask. You did turn it on did you? There is the button on the mirror that turns it on and off.
 
You might check the electrical connector to the mirror. It is located just above the mirror in the cable running behind the cover attached to the window. Perhaps there is a bit of poor contact there. Are you getting any display in the mirror at all? Are any of the lights working? The Air Bag light is in the bottom of the mirror, does it still work? I do not think it is a problem with the power to the mirror as it shares power with several other things in the interior and you would know if a fuse was blown. Also do not think it is a problem with the inputs as there are two separate inputs as discussed before.

My nephew has a 2004 Silverado, the rear view mirror has both the temp and compass option but for some reason this is inoprative at times, thats to say it works for a few miles then stops, has anyone taken these mirrors to bits, will they come apart or are they sealed like almost everything else is these days, i'm thinking that this is most likely a bad connection, a bad wire or a bad solder joint on the main PCB inside the mirror, was wondering if they have ever stripped a mirror down to board level for repair, does anyone know if the board is epoxy resined in or removable, I'm just trying to save time if this item is sealed or not repairable we can check the local breakers,
Anyone had this issue before
 
Thanks

Try the Chevy Silverado and GMC Sierra Electrical and Computer Issues discussion.

Ok, so it's 4 years later, but was there ever a resolution on this? I'm having the same issue....seems like it worked intermittently and then finally just died and won't come on at all.
