My heater AND my airconditioner does not work. I already have to replace my ac compressor, but my heater is not working either. A mechanic said they have to pull the whole dash off to replace the piece that opens and closes the door to allow the heat into the car. Does that make sense? Could there possibly be some other reasons?
