Question about 2002 Chevrolet Blazer
Thermometer shows DC instead of outside temperature
That is actually OC meaning there is an open circuit in the system some where, with out a signal generator at home to test the system, you are on a guessing mission, i would try a outside/ambient air temp sensor first, cheapest and easy to do it on the in front behind the grille on the pass side of the radiator , if this is not it it could be a wiring issue or it needs a new mirror which you have to calibrate the compass in after replacement
