articles. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
Before performing diagnosis of the A/C high pressure switch, verify that the refrigerant system has the correct refrigerant charge, (Refer to REFRIGERANT SYSTEM SERVICE EQUIPMENT) .
- Disconnect and isolate the negative battery cable.
- Disconnect the wire harness connector from the A/C high pressure switch.
- Using an ohmmeter, check for continuity between both terminals of the A/C high pressure switch. There should be continuity. If there is not continuity, replace the faulty A/C high pressure switch. If there is continuity, test the A/C high pressure switch sense circuit and repair as required, (Refer to ELECTRICAL/WIRING DIAGRAM INFORMATION - DIAGNOSIS AND TESTING) .
