Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off before starting.

2. Inspect Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the A/C fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity. Replace if blown.

3. Check Refrigerant Level

Connect a pressure gauge to the low-pressure service port of the A/C system.
Check the readings against the manufacturer's specifications.
If the refrigerant is low, proceed to recharge the system.

4. Assess the A/C Compressor

Locate the A/C compressor and visually inspect for leaks or damage.
Check if the compressor clutch is engaging when the A/C is turned on.
If the clutch is not engaging, further diagnose the electrical supply.

5. Replace Cabin Air Filter

Locate the cabin air filter compartment (usually behind the glove box).
Remove the old filter and inspect for dirt and blockages.
Install a new cabin air filter, ensuring it is oriented correctly.

6. Recharge A/C System (if necessary)

Using an A/C refrigerant charging kit, connect to the low-pressure service port.
Follow the instructions on the refrigerant can to add the correct amount of refrigerant.
Monitor the system as you charge to ensure the compressor engages.
