Q: Fresh air fan not working

asked by on

The fresh air fan on my car is not working.

The blower fan for your air conditioning and heater failing is a common problem. I would recommend having a qualified mechanic, such as one from YourMechanic, to diagnose what is causing your AC fan to not work. It is possible that the switch that controls the speed of the fan may be faulty, or the blower resistor unit may be bad. The mechanic will be able to pinpoint which of these issues is the underlying cause so that it may be fixed.
