Mine quit working too. It will blow but the compressor will not engage. Ford told me it was an ambient air temperature sensor. When I researched it it show 3 diff air temperature sensors: 1 behind the dash just below steering wheel to the right, 1 in the actual vent/blower assembly, and 1 under the hood mounted on the upper radiator mount.
