A/C System Inspection

A/C System Inspection

NOTE: For A/C system noise, go to the A/C system noise check. A/C System Noise Check

Before troubleshooting any problem with the air conditioning system, other than noise, do the following:

1. Check the A/C condenser (A) for material clogging the fins (dirt, insects, etc.). If the A/C condenser is clogged or restricted, 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 completely.

2. Check the A/C condenser for fin damage (bent fins). If any of the A/C condenser fins are bent, try to comb them straight. Do the refrigerant leak check A/C Refrigerant Leak Check to check for leaks if there is visible damage to the A/C condenser. If the A/C condenser is leaking or the fins cannot be straightened, replace the A/C condenser. Service and Repair

3. Check for kinks or sharp bends in the A/C lines and hoses, (which can greatly reduce system performance). If any of the A/C lines and hoses are kinked or bent, replace them. Service and Repair






4. 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. If there is any indication of leaks, do the refrigerant leak check A/C Refrigerant Leak Check to confirm the leak(s).

5. Inspect the drive belt for physical damage or signs of slippage. Testing and Inspection If the drive belt is damaged or shows signs of slippage, replace it and recheck.

6. Check the dust and pollen filter. If the dust and pollen filter is clogged, replace it. Service and Repair

7. Check for HVAC DTCs using the Self-diagnostic Function. Reading and Clearing Diagnostic Trouble Codes If there are any DTCs, go to the appropriate troubleshooting. Reading and Clearing Diagnostic Trouble Codes

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 compressor clutch armature plate (A) is rotating at the same speed as the pulley and is engaging. If the A/C compressor clutch is not engaging properly, go to A/C compressor clutch circuit troubleshooting. A/C Compressor Clutch Circuit Troubleshooting

10. Check that the A/C condenser fan (B) and the radiator fan (C) operate when the A/C compressor clutch is engaged and blow air toward the engine compartment. If one or both of the fans is not working properly, refer to the symptom troubleshooting.

11. Check that the A/C operates at each position of the blower fan switch (except OFF). If the A/C does not operate at all blower fan switch positions, refer to the symptom troubleshooting.

12. Check that the engine idle speed is correctly maintained when the A/C is switched on and off (A/C compressor clutch is engaged and disengaged). If the idle speed increase more than 100 rpm when the A/C compressor engages, confirm that the A/C compressor is the cause of the idle speed increase. Replace the A/C compressor, if necessary.

13. Do the A/C system test. A/C System Test If the vent temperature is out of range, repair according to the pressure test table. A/C System Test
