Why does my AC and heat does not work

Hello, Check the fuse for your blower motor. If you are seeing everything come on, but no air, the blower motor is likely not spinning/pushing air. There are a couple of other reasons as well. -blower motor relay -blow motor resistor -blower motor -bad control unit (the part you use to turn on the A/C) -bad wiring The most likely suspects are the fuse, relay, and blower motor resistor, followed closely by the blower motor. Test before you invest.
