A/C System Inspection

A/C System Inspection

Before troubleshooting any problem with the air conditioning system, do the following.

1. With the ignition switch in LOCK (0), inspect the A/C components, the pressure lines, and the hoses for stains that may indicate a refrigerant or a A/C compressor oil leak.






2. Check the A/C condenser for material clogging the fins or for damage to the fins:

- Carefully clean any material from the A/C condenser (A) fins with water and detergent. If deeper cleaning is required, clean the fins with Honda brite cleaner (P/N 08732-0020B).
- Be sure to dry the A/C condenser completely.
- Refer to the Refrigerant Leak Check A/C Refrigerant Leak Check to confirm leaks if there is visible damage to the A/C condenser.





3. Inspect the drive belt Testing and Inspection.

4. Make sure no material is blocking the air flow to the A/C condenser.

5. Check the dust and pollen filter. Replace it if it is clogged Service and Repair.

6. Check for kinks or sharp bends in the A/C lines and hoses, which can greatly reduce system performance. Replace A/C lines and hoses if they are kinks or damaged Service and Repair.

7. Start the engine, turn the air conditioning system on, and allow it to run for a few minutes and reach stable operation.

- Check that the A/C operates at each position of the blower fan switch (except OFF). If the A/C does not operate, refer to the Symptom Troubleshooting.
- Check that the A/C compressor clutch (A) is engaged. The pressure plate should be rotating at the same speed as the pulley. If the pressure plate does not engage, refer to the Symptom Troubleshooting.
- Check that the radiator fan (B) and A/C condenser fan (C) operate when the A/C compressor clutch is engaged. If either fan fails to operate when the A/C compressor clutch is engaged, refer to the Symptom Troubleshooting.
- Check that the engine idle speed is correctly maintained when the A/C is switched on and off and the A/C compressor clutch is engaged and disengaged.
