Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle's battery to ensure safety during the repair.
Tools required: OBD-II scanner, refrigerant gauge, socket set, torque wrench, and screwdrivers.

2. Check and Recharge Refrigerant

If refrigerant levels are low, locate the low-pressure service port.
Attach the refrigerant gauge and add the appropriate type of refrigerant per manufacturer specifications.
- Common refrigerant: R134a or R1234yf (verify which is suitable for your model).
Monitor pressure readings to achieve the optimal level.

3. Replace Cabin Air Filter

Remove the glove box to access the cabin air filter compartment.
Take out the old cabin air filter and clean the housing.
Install a new cabin air filter, ensuring it is positioned correctly for airflow direction.
Reassemble the glove box.

4. Inspect and Repair Components

Visually inspect the AC compressor, hoses, and seals for any signs of wear or leaks.
If the compressor is faulty, disconnect the electrical connector and remove the mounting bolts.
Replace the compressor with a new unit, ensuring all connections are secure and properly tightened to the specified torque.

5. Test System Functionality

Reconnect the battery and start the vehicle.
Turn on the AC system to check for proper operation.
Monitor the system for any unusual noises and ensure it is blowing cold air.
