Circuit diagram
Normal operation of magnetic clutch
The magnetic clutch is supplied with battery voltage as shown:
1. A/C and blower switches are turned ON.
2. ECU receives signal that A/C and blower switches are ON and creates ground circuit.
3. A/C relay is magnetized and contact is closed.
4. Battery voltage is applied to magnetic clutch and clutch locks.
Note: The ECU also controls the additional fan and magnetic clutch operation, depending on engine load.
Step 1
1. Run the engine at idle.
2. Turn the A/C switch and blower switch ON.
3. Measure the voltage at terminal wire (G) of the magnetic clutch connector.
Step 2
1. Check for poor connection of the magnetic clutch ground wire eyelet.
2. If necessary, repair the connection.
3. If correct, replace the magnetic clutch.
