Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety.
Wear safety goggles and gloves.

2. Recharge the AC System

Tools Required: Refrigerant gauge, refrigerant canister
Ensure the engine is off and connect the refrigerant gauge to the low-pressure service port.
Start the engine and turn the AC to maximum cold.
Follow the gauge instructions to charge the system with refrigerant until the correct pressure is reached.
Disconnect the gauge and securely cap the service port.

3. Inspect and Replace AC Compressor (if needed)

Tools Required: Socket set, torque wrench, belt tensioner tool
Remove the drive belt by loosening the tensioner.
Disconnect electrical connectors and refrigerant lines from the compressor.
Remove the compressor mounting bolts and take out the compressor.
Install the new compressor, ensuring the correct orientation.
Reconnect the refrigerant lines and electrical connections.
Reinstall the drive belt and tension to specifications.

4. Replace Cabin Air Filter

Tools Required: None
Locate the cabin air filter housing (usually behind the glove box).
Remove the glove box or cover to access the filter.
Take out the old filter and insert the new one, ensuring proper airflow direction.
Reassemble the glove box or cover.

5. Final Checks

Reconnect the battery and start the vehicle.
Set the AC to maximum and verify that cool air is flowing from the vents.
Check for any abnormal noises or leaks around the AC compressor.
