Compressor Clutch: Symptom Related Diagnostic Procedures
When the air conditioning switch and the fan control knob (fan switch) are turned on with the engine running, current flows through the compressor relay
to activate the magnetic clutch.
The air conditioning can be stopped by turning of the air conditioning switch or the fan control knob (fan switch). However, even when the air
conditioning is in operation, the electronic thermostat, the pressure switch or the Powertrain Control Module (PCM) is used to stop the air conditioning
temporarily by turning off the magnetic clutch in the prearranged conditions to reduce the engine load which is being caused by the rise in the engine
coolant temperature, and the acceleration of the vehicle, etc. For the inspection of the relays, switches and units in the table, see "Individual Inspection".
