Diagnosis Information

1. Connect an approved R-134a recovery/recycling station to the A/C system.

2. Start the engine and turn on the A/C system.

3. Check the system pressures.
- It there is normal pressure, or at least some pressure reading on the high side (some refrigerant in the system), go to REPAIR PROCEDURE A.
- If there is no pressure (no refrigerant in the system), go to REPAIR PROCEDURE B.
