Lately, while going through the car wash in Phoenix (from 115 deg to 75 deg. very quickly) my outside air temp. digital readout in the rearview mirror gets stuck at 75 and slowly rises over time. Where is the air temp. sensor located on a 2001 Suburban K2500. It can last for a few days like this, then starts working again. I assume the sensor is accumulating water or can't handle the extreme change in temperature as this did not happen in the wintertime.
thanks.
