Solution

1. Preparation

Tools Required: OBD-II scanner, refrigerant gauge, multimeter, socket set, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Refrigerant Recharge

Sub-steps:
1. Connect the refrigerant gauge to the low-pressure service port of the AC system.
2. Check the current refrigerant level against specifications; if low, proceed to recharge.
3. If recharging, connect a refrigerant canister to the gauge and follow instructions for adding refrigerant until levels are correct.
4. Disconnect the refrigerant gauge and ensure the service port cap is securely replaced.

3. AC Compressor Inspection

Sub-steps:
1. Locate the AC compressor (usually near the front of the engine).
2. Check the electrical connector; ensure it is secure and free of corrosion.
3. If the compressor is not engaging, test the AC relay by swapping it with a similar relay in the fuse box to check for functionality.
4. If the compressor is faulty, it will need to be replaced.

4. Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter access panel (usually under the glove compartment).
2. Remove the panel by unscrewing any screws or unclipping it.
3. Take out the old cabin air filter and replace it with a new one, ensuring the airflow direction is correct.
4. Reattach the access panel securely.

5. Final Check and Reassemble

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the vehicle and turn on the AC to the maximum setting.
3. Monitor the air temperature and listen for unusual noises.
4. Check for any leaks around the AC components.
