Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the vehicle to cool down if it has been running.

2. Replace Blown Fuse

Locate the AC fuse in the fuse box.
Remove the blown fuse with a fuse puller.
Replace it with a new fuse of the same amperage.

3. Recharge Refrigerant

Connect the refrigerant gauge set to the low-pressure service port of the AC system.
Check the current refrigerant level; if low, proceed to recharge.
Attach the refrigerant can to the gauge set and open the valve slowly to add refrigerant until the desired pressure is reached as per the specifications in the vehicle manual.
Remove the gauge set and recap the service port.

4. Replace Cabin Air Filter

Locate the cabin air filter housing, typically behind the glove compartment.
Remove the glove compartment by unscrewing or unclipping it.
Open the filter housing, remove the old filter, and install a new cabin air filter ensuring the airflow direction matches the marked arrow on the filter.

5. Inspect and Repair AC Compressor

If the compressor is not engaging, check the electrical connections and relay.
If the compressor is damaged or leaking, remove it by disconnecting the electrical connector and the refrigerant lines (ensure refrigerant is properly recovered).
Install a new compressor, reconnect the refrigerant lines, and electrical connector according to specifications.

6. Test the AC System

Reconnect the battery.
Start the engine and turn on the AC to check for proper operation.
Monitor the system for any unusual sounds or performance issues.
