My ac doesnt work but the heater does. I can change it on the deal inside the car it works i can change from heat to defrost to vent and all that good stuff but when i try to change my fan speed that part of the switch doesnt work.

Not cool sence its mid winter and cold !BUt i want to get the fan speed working through the fan speed switch again what do i do?Pleese Help me!
