A/C Compressor Clutch, A/C Condenser/Radiator Fans Inoperative, Blower and Heater Controls Work (With A/C)

The A/C compressor clutch and the A/C condenser/radiator fans are inoperative, but the blower and heater controls work

Diagnostic Procedure:

1. Probable cause: A/C pressure sensor circuit malfunction

2. Do the A/C pressure sensor troubleshooting

3. (R18A1 engine): A/C pressure sensor circuit low voltage, P0532 A/C pressure sensor circuit high voltage P0533

4. (K20Z3 engine): A/C pressure sensor circuit low voltage, P0532 A/C pressure sensor circuit high voltage P0533

5. NOTE: The A/C pressure sensor can malfunction without setting a DTC
