Magnetic Clutch Does Not Operate (Condenser Fan Operates)

Magnetic clutch does not operate. (Condenser fan operates normally.)

Step 1 Measure voltage at compressor connector







1. Run the engine at idle.
2. Turn A/C and the blower switches ON.
3. Measure the voltage at the following terminal wire of the compressor connector.

Step 2 Measure voltage at magnetic clutch connector







- Measure the voltage at the following terminal wire of the magnetic clutch connector.

Step 3 Check magnetic clutch







1. Disconnect the magnetic clutch connector.
2. Check for continuity between the magnetic clutch and a body ground.

Step 4 Check thermal protector







1. Turn the air conditioner OFF for about 10 minutes.
2. After 10 minutes, check for continuity of the thermal protector.

Step 5 Measure voltage at refrigerant pressure switch No.1







- Measure the voltage at the following terminal wires of the refrigerant pressure switch No.1 connector.

Step 6 Measure refrigerant pressure




1. Turn the ignition switch OFF.
2. Connect the high-pressure hose of the manifold gauge to the high-pressure gauge fitting.
3. Measure the refrigerant pressure at the high-pressure side.

High-pressure side: Above 450 kPa (4.6 kgf/cm2, 65 psi)

4. If not as specified, check the refrigerant system by referring to the troubleshooting information in the Insufficient Cooling/No Cooling/Intermittent Cooling symptom chart.
5. If correct, replace refrigerant pressure switch No.2 with cooler pipe No.2.
