Condenser Fan Does Not Operate
Step 1 Check condenser tan operation1. Disconnect the condenser fan connector.
2. Apply 1 2V to terminal (BLU/WHT) and ground terminal (BLK) 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 ~lowing terminal wire of the condenser fan connector.
Step 3 Measure voltage at condenser fan relay
1. Run the engine at idle.
2. Turn the A/C and blower switches on.
3. Measure the voltage at the following terminal wires of the condenser fan relay connector. Replace the condenser fan relay if necessary.
Step 4 Measure voltage at A/C dual pressure switch
Measure the voltage at the following terminal wires of the A/C dual pressure switch.
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.
