BSullivan Posted November 22, 2010 Report Share Posted November 22, 2010 2002 Escalade, 3-4 months ago, during 90 degree weather, outside air temp began reading lower and lower. By about day 4 it read -45 degrees then OC. After checking the net, I decided to change the outside temp sensor located behind the grill. Changed it a couple of days ago with a sensor from local Caddy dealer and temp still reads OC. Is there anything else before the dealership mechanic is in my pocket?
