Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on the electrical system.

2. Recharge Refrigerant

Tools Required: AC refrigerant gauge, refrigerant canister
Connect the refrigerant gauge to the AC low-pressure service port.
Check the gauge readings; if low, add refrigerant according to the manufacturer's specifications.
Ensure the AC compressor is running while adding refrigerant.

3. Replace Cabin Air Filter

Tools Required: Screwdriver or trim removal tool
Locate the cabin air filter compartment, typically behind the glove box.
Remove the screws or clips securing the cover and take out the old filter.
Install the new cabin air filter, ensuring it is oriented correctly.

4. Inspect and Replace AC Compressor (if necessary)

Tools Required: Socket set, torque wrench
If the compressor is damaged, disconnect the electrical connector and refrigerant lines.
Remove the mounting bolts securing the compressor to the engine.
Install the new compressor, ensuring to torque the bolts to the manufacturer's specifications.
Reconnect the refrigerant lines and electrical connector.
