3000GT AWD V6-2972cc 3.0L DOHC Turbo 24 Valve (1996)
Magnetic Clutch Relay: Testing and Inspection
Air Conditioning Switch And Relay Circuit
To test the Air Conditioning Relay, located in the engine compartment, proceed as follows:
COMPONENT TEST
1. Remove the A/C relay.
2. Using an ohm meter, check for continuity between terminals 3 and 1.
Continuity: ............................................................................................................................................................................................ Should exist
3. Apply 12vdc across terminals 3 and 1 of the relay.
4. Using an ohm meter check for continuity between terminals 4 and 5.
Continuity: ............................................................................................................................................................................................ Should exist
HARNESS TEST
1. Using a volt meter, check for voltage between harness terminal 4 of the A/C relay and ground.
Voltage: ............................................................................................................................................................................................. System voltage
2. Turn the key to the OFF position and disconnect the ECU connectors.
3. Turn the key, A/C and blower switches to the ON position and check for voltage at harness terminal 22 of the A/C relay.
Voltage: ............................................................................................................................................................................................. System voltage
4. Turn the key to the OFF position.
5. Using an ohm meter check for continuity between ECU harness terminal 22 and relay harness terminal 1.
