This question depends on the make model and year of the vehicle to answer.
It may also require the AC and heating type depending on the vehicle.

Assuming you are asking about the ac compressor, there would be two possibilities, blown fuse or low on freon.
Check for a blown fuse in fuse block and also at the top of the compressor Bad switch Bad compressor clutch
Yes there is.
The low pressure switch could be activated because the system is low on freon.
If the belt's good, check the compressor clutch.
fuse 21
There is no fuse for the compressor itself, if the compressor is not working, the low pressure switch has activated and there is not enough refrigerant in the system. Have your AC system serviced by a good shop or your local Chrysler dealer.
There is a fuse for the air conditioner and one for the fan. You have a power source to the fuse. From the fuse the relay gets it's power and then the fan and or the air conditioner compressor.
Mabe your compressor clutch is no good. A good way to check it is to disconnect the wires that go to compressor then turn your ac on. If it does not burn the fuse it means your compressor clutch is bad.
