Solution

1. Preparation

Gather tools and parts necessary for the repair.
Disconnect the vehicle's battery to ensure safety during repairs.

2. Check Refrigerant Levels

Tools Required: Refrigerant gauge, refrigerant refill kit (if needed).
Connect the refrigerant gauge to the low-pressure service port.
Read the pressure; if low, add the appropriate type of refrigerant (e.g., R-134a).
Ensure not to overfill the system.

3. Inspect A/C Compressor

Tools Required: Socket set, torque wrench.
Locate the A/C compressor and visually inspect it for damage.
Disconnect the electrical connector and check for continuity using a multimeter.
If the compressor is faulty, replace it by removing the mounting bolts and disconnecting the refrigerant lines (ensure to recover refrigerant if necessary).

4. Replace Cabin Air Filter

Tools Required: Screwdriver or socket set (depending on filter housing).
Locate the cabin air filter (usually behind the glove box).
Remove the filter cover and take out the old filter.
Install the new filter, ensuring the airflow direction matches the markings.

5. Check and Clean Electrical Connections

Tools Required: Wire brush, electrical contact cleaner.
Inspect all related electrical connections for corrosion or damage.
Clean connections with electrical contact cleaner and reconnect securely.

6. Test A/C Control Module

Tools Required: OBD-II scanner.
Reconnect the battery and start the vehicle.
Use the scanner to check the A/C control module for any fault codes.
If codes are present, follow the manufacturer's procedure for troubleshooting or replacing the module.
