Refrigerant Pressure Switch Inspection

WARNING: This page is about a different car, the 2004 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.

Install the SST (gas charging set).
Disconnect the refrigerant pressure switch connector.
Verify the high-pressure side reading of the SST (manifold gauge) and continuity between the refrigerant pressure switch terminals.
- If there is any malfunction, replace the refrigerant pressure switch.
