Car is a 1997 Subaru wagon. AC and Heat work, but only when fan is set to 4. Fan does not even come on for 1, 2 or 3. Everything else works. Is there a part for just the blower control that I can replace, or do I need a new HVAC controller?
On most cars there is a resistor usu. mounted very close to the blower motor.That is usu what goes bad.setting 4 is full power the others are less than that by way of the resistor.
