2004 chevy impala heater issues

Asked by Dec 23, 2017 at 05:17 PM about the 2004 Chevrolet Impala

Question type: Maintenance & Repair

I recently bought this car from a private owner and I did not thoroughly  investigate the heating components because it worked in the setting it was set to. However one day I switched the flow of air from the floor to the defrost setting and it quit working. You can hear a slight buzzing or humming sound start everytime you rotate the dial for the air flow. for example from face to dash or dash to floor. Also they have removed the radio that was in there and just cut the wires Im wondering if maybe they shorted something out or backfed and caused a short..... I have the radio but I could use some diagrams so I can hard wire it back in or open to suggestions and help.

I had a similar issue with mine. There is a module that controls the air diverter. The system turns off or down the fan motor so the diverter can move to the proper location. question is, does the fan blow air in the other locations? You should set the controls to Floor, Dash(face), and Defrost(Dash) (All the way Right, Straight up, and all the way left) and see if the fan works. If so, see if the air is only coming from the location the knob is pointed to. If not remove the glove box and replace the AC Heater Temperature Actuator.
