Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Recover and Replace Refrigerant

Tools Required: Refrigerant recovery machine, manifold gauge set, vacuum pump, refrigerant.
Connect the recovery machine to the AC system and recover the refrigerant.
Replace the receiver-drier if it is clogged or damaged.
Evacuate the AC system using the vacuum pump for at least 30 minutes.
Recharge the AC system with the correct type and amount of refrigerant as specified in the owner's manual.

3. Inspect and Repair Components

Tools Required: Socket set, screwdrivers, AC compressor tool kit.
If the compressor is not engaging, check the electrical connections and fuses related to the AC system.
If necessary, replace the AC compressor by:
- Removing the serpentine belt.
- Disconnecting the refrigerant lines.
- Unbolting the compressor from the engine.
- Installing the new compressor and reconnecting all components.

4. Clean AC System

Tools Required: Compressed air, cleaning solution.
Remove and clean the cabin air filter.
Clean the AC condenser using compressed air to remove any debris obstructing airflow.
