2000 Blazer LT 4 wheel drive.Has the information center(compass and shows outside temp and fuel economy etc)There seems to be a problem with the temp sensor. Does anyone know where the temp sensor is located and if it is an easy repair? Any advise on this problem please.

Auto matic AC/heater controls?
The sensor is on right side of radiator support baffle.
The HVAC module takes care of all inputs and outputs on the outside tempt sensor.
You need a HAVC capable scanner to read out the data and codes in the AC/heater control module to see what is going on in there.
