Default No AC and the heat only blows on defrost after wiring aftermarket stereo.
My fiancé wired an aftermarket speaker and amp into my 2009 H3 last night. Now my AC blows hot air and my heater will only blow through defrost even when put in the other settings. He has tried and tried to find a solution and cannot. Can anyone help?
