Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked in a well-ventilated area and the engine is off.
Disconnect the battery to prevent electrical issues while working on the A/C system.

2. Inspect and Replace A/C Fuse

Locate the A/C fuse in the fuse box (refer to the owner's manual for specific location).
Remove the fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown.
Reinstall the new fuse and reconnect the battery.

3. Check Refrigerant Level

Connect a refrigerant gauge to the service port of the A/C system.
Check the pressure readings; if low, it indicates a refrigerant leak.
If needed, evacuate the system using a vacuum pump, and recharge with the correct type and amount of refrigerant (R134a or R1234yf as specified).

4. Replace Cabin Air Filter

Open the glove compartment and remove it.
Locate the cabin air filter compartment, typically behind the glove box.
Remove the old filter and replace it with a new one, ensuring the airflow direction is correct.
Reassemble the glove compartment.

5. Inspect A/C Compressor

Start the vehicle and turn on the A/C.
Check if the A/C compressor engages and the clutch is spinning.
If not, check the electrical connections and relay; replace if necessary.

6. Test Drive and Monitor

Test drive the vehicle with the A/C on to ensure proper cooling and performance.
Monitor for any unusual noises or smells.
