Failure of the air conditioning compressor is common because moisture or clogs in the air conditioning system will place high stress on the compressor. Compressor clutch failure is much more common on older vehicles, but some modern compressors still utilize an A/C compressor clutch to turn the compressor on and off. In general, A/C compressors tend to fail after 60,000-70,000 miles, but that time may be lengthened depending on use, demand, and operating conditions.
1. Remove compressor, receiver drier or accumulator, orifice tube or expansion valve. 2. Flush the condenser and evaporator using NON-OIL BASED A/C flush. On expansion valve systems. The valve must be removed before the evaporator can be flushed. Flushed condensers from outlet to inlet and evaporators from inlet to outlet. 3. Drain all the oil from the new compressor and dispose of according to local, state and federal laws.NOTE: if you compressor has a drain plug you will need to open it up and drain what oil is in there too. 4. Install half oil charge into the compressor and the remainder throughout the system. Turn compressor shaft 8-10 full revolutions to ensure front seal and other internal parts are lubricated. 5. Install new receiver drier or accumulator and new orifice tube or expansion valve. 6. Evacuate the A/C system for a minimum of one hour. 7. After evacuation installs half the refrigerant charge and let the system set for 1 minute. This will allow the refrigerant to pick up oil and spread more evenly throughout the system. 8. Turn on the A/C system with the engine running and check to see if cold air is now coming out of the air duct.

Shutdown maintenance must wait for the whole A/C compressor cooling down and the compressed air is safely released, meanwhile, the maintainer needs to avoid any vent closing their relevant isolating valve as much as possible. 3. Adopted no-corrosive safety solvent to clean out the component is very important. Flammable, explosive and volatile detergent is banned. 4. It is of great importance to examine protective system regularly to make sure their sensitivity and reliability, once a year is okay.
