Description & Operation: Receiver/Drier

WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, and 2002 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

The receiver/drier is located in the engine compartment near the dash panel on the passenger side of the vehicle. The receiver/drier incorporates a sight glass for visual diagnosis of the refrigerant system.

High-pressure liquid refrigerant from the condenser flows into the receiver/drier. A drying agent, called a desiccant, is used to remove any traces of moisture from the refrigerant system. The receiver/drier also performs a filtering action to prevent foreign material in the refrigerant from contaminating the expansion valve. In addition, during periods of high demand air conditioner operation, the receiver/drier acts as a reservoir to store surplus refrigerant. The A/C refrigerant must be removed from the system before removing the receiver/drier using a refrigerant recovery machine. Replace the receiver/drier if an A/C system is left open for an extended period of time. The receiver/drier cannot be repaired and, if faulty, must be replaced.
