When I turn the Fan knob to the lowest and medium setting there is no air. The medium setting used to work but has gotten very weak . Only when I turn the knob to the highest setting does any air come out.

If the fan is only working on the highest setting, most likely the blower motor relay needs replaced.

Would the relay also be called a resistor? I was just wondering. Thanks for the help.

Yes, it's the resister. I have no idea why I said relay. Too many 15 hour days. I need sleep. lol

Let me know if it takes care of the problem.
