WARNING: This page is about a different car, the 1998 Dodge Intrepid and 1998 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
There are 2 methods for performing this procedure. The first method involves the use of a scan tool and a clamp-on Thermocouple (80PK-1A). Set scan tool to LH CLIMATE CONTROL, SYSTEM TEST and PARTIAL CHARGE TEST. See SCAN TOOL METHOD.
The second method uses a manifold gauge set, a clamp-on thermocouple, and REFRIGERANT CHARGE LEVEL table. See MANIFOLD GAUGE SET METHOD.
