Follow the manufacturer's instructions to recover the refrigerant safely.
Dispose of the refrigerant according to local regulations.

3. Inspect A/C Components

A/C Compressor: Remove the belt and disconnect the electrical connector. Inspect for signs of wear or failure.
Condenser: Remove any debris obstructing the condenser. Look for signs of leaks or damage.
Hoses and Connections: Inspect all hoses for cracks, wear, or leaks.

4. Repair or Replace Components

If the compressor is faulty, replace it:
- Remove the mounting bolts and detach the compressor.
- Install the new compressor and torque the bolts to the manufacturer specifications.
If there are leaks in the hoses, replace the affected hoses.

5. Recharge A/C System

Connect the A/C service manifold to the system.
Follow the manufacturer's guidelines to charge the A/C system with the correct type and amount of refrigerant.
Monitor the system pressures to ensure they are within normal operating ranges.
