Diagnostic Aids

To diagnose an intermittent fault, check for following conditions:

• Poor connection at PCM. Inspect connections for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal-to-wire connection.
• Inspect wiring harness for damage. If wiring harness appears to be okay, observe A/C clutch while moving connectors and wiring harnesses related to the A/C. A sudden clutch malfunction will indicate source of intermittent fault.
