My heater, fan, and defrost stopped working. Nothing happens when I turn the switch back and forth. This went out a month ago. What could this be?

Hi myscottiedog,
It could be a bad fan motor or a blown fuse. Check the underdash fuse box for any blown fuse.
If the maximum speed is working, then the fan motor resistor is bad. If alll speeds are not working, unplug the blower motor connector and apply battery voltage to the terminals to test the motor.
