Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety.
Allow the engine to cool down before starting.

2. Recharge Refrigerant

Tools Required: Refrigerant gauge set, refrigerant canister, safety goggles, gloves.
Connect the low-pressure gauge to the AC service port.
Check the refrigerant level; if low, proceed to recharge.
Attach the refrigerant canister to the gauge set and open the valve.
Monitor the pressure and add refrigerant until it reaches the manufacturer's recommended level (typically around 30-40 psi for low pressure).
Disconnect the gauge set and replace the service port cap.

3. Replace AC Components (if necessary)

Tools Required: Socket set, wrench set, torque wrench.
If the compressor is faulty, remove the drive belt by loosening the tensioner.
Disconnect electrical connectors and refrigerant lines from the compressor.
Remove mounting bolts and take out the compressor.
Install the new compressor, ensuring to torque bolts to manufacturer specifications.
Reconnect electrical connectors and refrigerant lines.

4. Inspect and Replace the Cabin Air Filter

Tools Required: Screwdriver or trim removal tool (if needed).
Locate the cabin air filter housing, typically behind the glove box.
Remove any screws or clips holding the cover.
Take out the old filter and install the new one, ensuring the airflow direction matches the markings.
Reassemble the housing.

5. Final Assembly and Testing

Reconnect the battery.
Start the engine and activate the AC system.
Check for proper operation, ensuring cold air flows from the vents.
