Outside temperature display on rear view mirror

Locate and remove the outside temperature sensor located in the left side rear view mirror on these North American S70's. When this sensor goes bad, the DIM display shows -34 ----

u might have to do that with the mirror but the air bag thing i would have a mechanic take a look at it but i think the air bag computer system is failing

2003 Chevy Silverado
our rearview mirror has gone off and the airbag light stays on.
i've determined that this is a fuse, the SIR fuse under the hood, but what I can't figure out is why it's blowing.
It's either something to do with when we hook up the lights to the trailer or it might be from where we installed a new car stereo.
I took it to the Chevy dealer for some other things and told them there was a fuse blown to the rearview mirror and to the airbag and just asked them to replace the fuse while it was in the shop.
on top of the $700 i was already spending, they charged me $98 to diagnose that it was a blown fuse and like $11 to change it, even though I already told them it was the airbag fuse. Highway robbery. And they wonder why we don't like 'em.

There probably is a fuse, and your owners manual should say it. If not that does not work, there may be a faulty thermometer, and the book will also list part #s, and more helpful, where it's at.

Temperature Display
The inside rearview mirror supplies a 5 volt signal circuit and low reference circuit to the ambient air temperature sensor. The inside rearview mirror monitors and records the voltage on the signal circuit of the ambient air temperature sensor. The inside rearview mirror uses this recorded voltage to display the temperature on the temperature display portion of the compass/temperature display. The temperature display will show "ICE" when the ignition is first turned on and the current temperature is 3°C (37°F) or below. The display will toggle between "ICE" and the actual outside temperature for approximately 4 minutes.
The mirror will display "OC" if the mirror senses a temperature of less than -40°C (-40°F).
the mirror will display a "SC" if the mirror senses a temperature of greater than 112°C (143°F).



Replace the inside rearview mirror with compass. Refer to Inside Rearview Mirror Replacement .

Have your resolved the issue stated above. I have been having the same problem. Now my display has stopped working completely.

The temperature display on the rear view mirror my 2002 Trailblazer LT is either way incorrect - like obviously too high or too low - but mostly just shows "OC" all the time. Is this an expensive fix? Is this an easy fix that I could do myself? What do I need to replace and how

Probably a burnt light bulb

I had this problem myself and come to find out it was a blown fuse which also controls the outside temp display and compass built into the rear view mirror. Check in your fuse box located under the hood on the driver side, open the big black box cover and locate the airbag fuse. Pull it out and check to see if it is burnt. Replace it if necessary.
Hope this helps you
