Cool exterior temperature reading stuck

I just wanted to let y'all know, I had a problem with the exterior temperature reading being stuck on 39 degrees on my climate control unit (I have the automatic climate controls.) I read a thread from another member that suggested to reset the sensor by pressing the "mode, front defrost, and rear defrost" buttons all at the same time. This instantly fixed my problem and prevented me from having to buy a new sensor and installing it. Hope this helps someone else! FYI: When this procedure was used, it reset the temperature to 70 degrees and then it started to drop until it reached the actual outside temperature.

Is there a procedure to reset the sensor for those of us without digital controls? I have this same issue on my temp. on the rear view mirror. I was going to buy the sensor this week sometime but dont want to waste the cash if its fixable.

I'm unsure if there is a procedure to fix the regular one other than pulling fuse or disconnecting the battery.

I do know that if the sensor is bad you usually get the letters OC in the display indicating Open Circuit.

That sums it up for me then. I have been getting that "OC" for a few months now.

Thats awesome, mine has been stuck on 50. Brought it to the stealership today. They told me it was the sensor, so they changed it. Then they came back and told me the controls were also broken. $400 for controls, i said no thanks, bastards
