Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety.
Allow the vehicle to sit for at least 30 minutes to cool down.

2. Inspect and Replace Refrigerant

Tools Required: Refrigerant gauge set, refrigerant canister, safety goggles, gloves.
Sub-steps:
- Connect the refrigerant gauge to the low-pressure port of the AC system.
- Check the pressure readings; if low, proceed to add refrigerant.
- Follow the manufacturer's specifications for the type and amount of refrigerant to add.
- Disconnect the gauge and check the system operation.

3. Replace the AC Compressor (if necessary)

Tools Required: Socket set, torque wrench, AC compressor replacement kit, new O-rings.
Sub-steps:
- Remove the serpentine belt by loosening the tensioner.
- Disconnect electrical connectors and refrigerant lines from the AC compressor.
- Unbolt the compressor from its mounting bracket.
- Install the new compressor using new O-rings and torque the bolts to the manufacturer’s specifications.
- Reconnect refrigerant lines and electrical connectors.

4. Replace Cabin Air Filter (if necessary)

Tools Required: None (optional: screwdriver).
Sub-steps:
- Locate the cabin air filter access panel (usually under the glove compartment).
- Remove the panel and take out the old filter.
- Install the new filter, ensuring the airflow direction matches the markings.
- Reattach the access panel.

5. Recharge the AC System

Tools Required: Refrigerant gauge set, refrigerant canister.
Sub-steps:
- After repairs, connect the refrigerant gauge to both the low and high-pressure ports.
- Follow the manufacturer’s guidelines to recharge the AC system with the appropriate refrigerant.
- Start the engine and let the AC run for a few minutes, monitoring the pressures.
