There is usually an on off button on the mirror. Double check to make sure it was not turned off. If that is not the case, then you can check your manual for the fuse location for the mirror. Typically the fuses are located inside the car either under the dash or by the kick panel. Once you read the manual you will find the referenced location of the fuse and can go from there.

Good luck

The interior rear view mirror has temperature and compass displays, but only work for a short time at start- up.I have tried unplugging the harness on the back of the mirror and cleaning contacts. It`s...

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 .

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

"Chevy Mechanic: Dave Nova
The problem is going to be a break in the circuit between the *SIR fuse and the yellow wire at the mirror connector. This wire travels through the relay block. You can check connections at the relay block and trace the wiring. You can also just run a new wire, it may be faster."


"Check for voltage on the yellow wire at the mirror connector with the key on. If there is voltage on the yellow wire then the problem is inside the circuit board in the mirror and the mirror will need to be replaced."

Dave Nova included the Fuse Block shown below in his post, but I see no "SIR" Fuse? * I just discovered it is a "Supplemental Inflatable Restraint (SIR) Fuse = AIRBAGS. The two photos below are MUCH closer to what you should have!

Hi there. The mirrors should have everything you need mounted to them if they are for an s10. There will be three screws on the external faceplate, under that three larger screws that go through the mirror directly to the door.

Rear view mirror does not change to night view

I have allot of experience with these mirrors, if your just stopped working it lasted longer than most, many never even made it out of factory warranty, the problem is the mirror not any fuse, the cost of the new unit is around $200.
