    Default Temp/Compass in Mirror?

    2004 Chevy Silverado. I have recently lost the temp and compass display on my mirror. Any ideas on what I might need to look for in order to get this operational again? I know that it is a minor issue but I kinda got use to looking up there and now there is nothing to look at. Thanks.

    Default same deal

    03 silverado and I got used to having that little display and it began to work only intermittently then finally quit all together. I took a plastic cover off of a small enclosure attached to the windshield and found a small circuit board. I unplugged and cleaned connections and replaced all parts. The airbag indicator is still working and the auto dim feature is functional. There is NOTHING on the interwebs about this problem. Any ideas appreciated. Next is just a new truck.

I will try cleaning the connections as suggested above, but would greatly appreciatge any other suggestions. I will post the results after I have cleaned the connections.

    mine did that real intermitent in the cold one day (back in minnesota) but aint done it since. though, now that i think of it, that may of been in the 03. huh.

    if it was the current truck, it hasnt been an issue since. i would guess its a connection issue, but thats me.

    Ok, you revived an old thread..but....see if this helps...this is from another forum that is full of auto repair geeks:

    "Some owners may comment of a SIR MIL and if equipped the temperature/compass display on the inside rearview mirror is inoperative. This concern may be caused by the 15 Amp Air Bag Fuse open. Reports from the field have shown in some cases circuit 1139 Yellow may be shorted to ground at the Left I/P Junction Block mounting bracket as shown below."

    To correct the concern repair the wiring as necessary and insulate harness and mounting bracket with foam tape to prevent a reoccurrences

    It'd also go away if they played Russian Roulette with a fully loaded M1911. Cheeeez, unplugging the airbags?

    I said the fuse....not the air bags themselves.

    Totally different things.
