I have a 2003 silverado, and I need to locate the outside air temperature (OAT) sensor which gives a reading in the rearview mirror. I think this sensor is usually located around the front bumper or grille opening somewhere, but I don't know what it looks like. If anyone can tell me exactly where to find it, that would be nice, and if you can provide a picture, that would be awesome. Thanks in advance!

 

# 3 is the sensor

 

Awesome reply! That's exactly what I was looking for. Thanks a lot !!

 

No problem.
