Why does my auto A/C only work on two fan speeds?

Most of the time this is caused by a bad blower resistor, which many times will be caused by a blower motor going bad and drawing too much current. If you only replace the resistor you may find you are doing it again in a short period of time. A good technician will run a current test on the fan motor to determine the cause of the resistor failure.
