    Default It's HOT outside! *Rearview mirror temp readout content*

    So the compass works fine on the rearview mirror, but it tells me that it's well over 100 degrees almost all the time. It was about 40 out this morning, but the mirror said it was 122.

    Whazzup with that?

    Is this regarding the '99 burb?

    Just to comment, Mine does same thing. Especially with defrost on, max heat and max blower. I think it messes with the sensor sometimes. Once you start driving the temperature becomes more realistic. Don't think its a defect just the location and how the sensor reads outside air.

    Not mine. It goes down a few degrees, but I've never seen it below 88.

    I'm not familiar with the burb's or that year, but I had a '97 sierra in which someone had installed an aftermarket temp/compass mirror.....and they mounted the outdoor temperture sensor too close to the radiator. That could be the problem if the gauge reads correctly when first starting out and then maintains the high temp after the engine is warmed up. If it starts out wrong to begin with, you might need to replace the sensor.

    That makes sense. I'll probably just replace the sensor at some point. Till then, I'll just pretend I'm actually driving in the Bahamas.
