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.

 

Temp sensor is behind the grill on the hood latch support (center of the radiator).

 

Is it easy to replace?
