Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working with electrical components.

2. Recover Refrigerant

Connect the recovery machine to the AC service ports.
Open the valves and allow the machine to recover the existing refrigerant.
Follow the manufacturer's instructions for the recovery machine.

3. Inspect and Repair Leaks

After identifying the leak location, remove any damaged components (e.g., hoses, o-rings).
Replace damaged hoses or components with new parts.
Ensure all connections are clean and free of debris.

4. Recharge AC System

Attach the manifold gauge set to the AC service ports.
Vacuum the system for at least 30 minutes to remove moisture and air.
Recharge the system with the correct amount of refrigerant (check specifications for the model).

5. Test AC Performance

Start the engine and turn on the AC to the maximum setting.
Monitor the temperature at the vents to ensure it cools properly.
Check for any leaks again using the UV dye method if necessary.
