first check all fuses related to the AC system. i think there are 3. if you can hear the blower motor from inside the car when the air is on, it is most likely the vacuum line from the intake manifold is off or broken. it is the rearleft most line coming off the manifold if looking from the front of the car. if you cant hear the blower motor, either the switch or blower motor are bad. it is most likely the fuse or vacuum hose though.

I have a 99 Ford F250 super duty. When I turn on the fan to the heater and AC I can hear air moving in to the vents. No air moves out of the vent on any setting. It is like all vents are closed. what could be the problem. I have replaced the switch. I check the blower motor.
