Drier, A/C Receiver: Operation

WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

The A/C receiver/drier performs a filtering action to prevent foreign material that may be in the refrigerant from contaminating the A/C expansion valve and the A/C compressor. Refrigerant enters the A/C receiver/drier as a high pressure, low temperature liquid. Desiccant inside the A/C receiver/drier absorbs any moisture which may have entered and become trapped within the refrigerant system. In addition, during periods of high demand operation of the A/C system, the A/C receiver/drier acts as a reservoir to store surplus refrigerant.

The A/C receiver/drier is integral to the A/C condenser and has no serviceable parts.

The A/C receiver/drier cannot be repaired and the A/C condenser must be replaced if the receiver/drier is leaking or damaged, or if an internal failure of the A/C compressor has occurred. Refer to CONDENSER, A/C, REMOVAL .
