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, pressure lines and hoses for stains that may indicate a refrigerant or a 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 fins with water and detergent.

- Be sure to dry the A/C condenser (A) completely.

3. Inspect the drive belt. Testing and Inspection

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

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

6. Start the engine, turn the air conditioning system on, and allow it to normalize for a few minutes.

7. Check that the A/C operates at each position of the blower fan switch (except OFF).






8. Check that the A/C compressor clutch (A) is engaged. The pressure plate should be rotating at the same speed as the pulley.

9. Check that the cooling fans (B) operate when the A/C compressor clutch is engaged.

10. Check that the engine idle speed is correct when the A/C is switched on and off, and when the A/C compressor clutch is engaged and disengaged.
