You either have a bad switch or you need to check your fuse or relay for your a/c. To check your switch: you need a multimeter or voltmeter. You'll need to get to the back of your switch, keep it plugged in and find your power wire to the switch. Then put the positive end of the voltmeter in the back of the connector into the power(don't push to hard or you'll damage the connector). Then put the negative end of the voltmeter on a good ground on your frame or something that touches your frame. You should get a voltage reading of 12 volts. If there's no voltage than somethings wrong with the wiring up to your switch. If there is voltage, than you need a new switch.

Turn the defroster on. If you have a separate AC switch, turn it on also. The AC should come on with the defroster automatically, but might not. If no AC, set the vent control to outside air instead of recirculate.
