Condenser Fan Does Not Operate (Magnetic Clutch Operates)
Condenser fan does not operate. (Magnetic clutch operates normally.)Step 1 Check condenser fan operation
1. Disconnect the condenser fan connector.
2. Apply battery voltage to terminal a and ground terminal b and verify that the condenser fan operates.
3. If the condenser fan does not operate, replace it.
4. If the condenser fan operates, go to Step 2.
Step 2 Measure voltage at condenser fan
1. Disconnect the condenser fan connector.
2. Run the engine at idle.
3. Turn the A/C and blower switches ON.
4. Measure the voltage at the following terminal wire of the condenser fan connector.
Step 3 Measure voltage at condenser fan relay
- Measure the voltage at the following terminal wires of the condenser fan relay connector.
Step 4 Measure voltage at refrigerant pressure switch No.2
- Measure the voltage at the following terminal wires of the refrigerant pressure switch No.2 connector.
Step 5 Measure refrigerant pressure
1. Connect the A/C manifold gauge set.
2. Operate the engine at 2,000 rpm and set the air conditioner to maximum cooling.
3. Measure the high-pressure side refrigerant pressure.
