A/C Compressor Clutch Circuit Troubleshooting
NOTE:
-
Do not use this troubleshooting procedure if the fans are also inoperative with the A/C on. Refer to the symptom troubleshooting index. See:
Testing and Inspection/Symptom Related Diagnostic Procedures/Heating/Air Conditioning

Before performing symptom troubleshooting, check for powertrain DTCs.
1. Check the No. 59 (7.5 A) fuse in the under-hood fuse/relay box, and the No. 3 (7.5 A) fuse in the driver's under-dash fuse/relay box.
Are the fuses OK?
YES - Go to step 2.
NO - Replace the fuse(s), and recheck.
2. Start the engine, and check the engine coolant temperature, throttle position, and idle speed (use the HDS PGM-FI data list if possible).
Are the coolant temperature, throttle position, and idle speed OK?
YES - Go to step 3.
NO - Troubleshoot and repair the cause of the high engine coolant temperature, low idle, or excessively high throttle position sensor reading.
3. Turn the ignition switch OFF.
4. Remove the A/C compressor clutch relay from the under-hood fuse/relay box, and test it.
Is the relay OK?
YES - Go to step 5.
NO - Replace the A/C compressor clutch relay.
5. Measure the voltage between the No. 1 terminal of the A/C compressor clutch relay 4P socket and body ground.
Is there battery voltage?
YES - Go to step 6.
NO - Replace the under-hood fuse/relay box.
