A/C System Inspection
A/C System Inspection
Before troubleshooting any problem with the air conditioning system, do the following:
1. Check for collision damage or body shop work.
2. Make sure the ignition switch is in LOCK (0). Inspect the A/C components, the pressure lines, and the hoses for stains that may indicate a refrigerant or a compressor oil leak.
3. 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 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 (A) 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.
4. Inspect the drive belt. Testing and Inspection
5. Make sure no material is blocking the airflow to the A/C condenser.
6. Check the dust and pollen filter, and replace it if it is clogged. Service and Repair
7. 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 kinked or damaged. Service and Repair
8. Start the engine, turn the air conditioning system on, and allow it to run for a few minutes and reach stable operation.
9. 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.
10. 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, or fails to disengage, refer to the symptom troubleshooting.
11. Check that the cooling fans (B) 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.
12. Check that the engine idle speed is correctly maintained when the A/C is switched on and off, and when the A/C compressor clutch is engaged and disengaged.
