Check the fuse . or it could be the CCM that's a black box to to left side of radiator . it houses 4 relays that cant be replaced (fuel pump , fan , A/C , AND SOMETIME ELSE I CANT REMEMBER ). replace it from any good parts store about $100.00 good luck!

Maybe the compressor clutch is not being sent power from the switch in the cab. I'd yank the panel out and have a look at the switch. FriPilot
Pressure test the convertor.
Low freon charge and faulty CCRM (Constant Control Relay Module).
Dirty injectors, air filter cloged, spark plugs need changed, catyletic converter stoped up
Assuming you are asking about the ac compressor, there would be two possibilities, blown fuse or low on freon.
its got toothpaste in the carby
wow, not at all. the camaros have 275 horse power and the mustang has 260 horsepower. Camaro would blow the doors off of a mustang.
check a/c compressor and belt.
If the noise sounds like a power steering whine it could be caused by the A/C compressor clutch bearing or the belt idler pulley.
Mabe your compressor is not kicking on for some reason. Check to see if the front of your compressor starts spinning when you turn it on. If it don't check to see if there is power to the wires that go to your compressor. If there is power you have a bad compressor. If there is not check the fuses or relays.
well, out of freon in A/C, because the pressure sensor not being energized. then a bad fuse on the A/C circuit, followed by open clutch on A/C compressor.
