I would start with the basics and look for a blown fuse - there should be a fuse for the air conditioning switches , A/C compressor clutch
fuse,compressor clutch relay,wiring,system needs recharging,bad compressor
When it stops working do you mean that it quits cooling or the a/c compressor goes bad ???? If it quits cooling and the a/c compressor is good then you either have a leak in the system or the system has a restriction. If the a/c compressor is bad then you have a lot of trash in the system from the first one that was replaced..............
too much oil in system or compressor not working properly are some possibilities
You should have the system checked by a repair shop that is certified to service A/C systems...if your ac system is not working it may be not be the compressor or the condenser at all...before replacing anything check the system for proper charge, check the metering device (either a TXV valve or an orifice tube depending on the vehicle) and check to make sure that the compressor clutch is functioning properly...and remember never disconnect any part of the A/C system without having the system evacuated first...hope this helps.
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.
The amount of oil charge required for an automotive AC system is specific to the car. There is not standard amount for all cars.
Only charge the system from the low pressure side.you could blow the can of freon up in your hand otherwise.
Always use safety glasses and gloves! To remove the A/C compressor you must evacuate system & properly dispose of old R-134A. Then unbolt and remove old compressor. (You should be certified to handle R-134A to charge system)
You need to properly evacuate A/C system, then remove compressor. Install new part, properly charge A/C system. Ensure you are using proper type and amount of compressor oil.
system may need to be evacuated prior to charging
Bad seal on compressor? Leak in system
Mechanical control system for an compressor?
