Q: Air not blowing

asked by on

The air only system on my car worked on high. Now, it is not working at all.

Hi. I am assuming you are talking about the a/c blower motor. I would say you have a bad blower motor resistor mounted on the blower case which would allow it to only work on high. But now, since the motor does not even work on high, the motor might be the cause of the problem. I would recommend you have a mechanic, like one from YourMechanic, inspect why your AC is working to its full potential.
