Solution

1. Preparation

Gather all required tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace A/C Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the A/C fuse and check for continuity using a multimeter.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Inspect and Recharge Refrigerant

Connect a refrigerant gauge to the low-pressure service port of the A/C system.
Check the refrigerant level; if low, proceed to recharge.
Use the appropriate refrigerant type (R-134a or R-1234yf as per vehicle specifications).
Follow the manufacturer's guidelines for the correct amount of refrigerant to add.

4. Inspect A/C Compressor and Clutch

Visually inspect the A/C compressor for signs of wear or leaks.
If the compressor clutch does not engage when the A/C is activated, check the electrical connections and relay.
If the compressor is faulty, it will need replacement.

5. Replace Cabin Air Filter

Remove the glove compartment to access the cabin air filter compartment.
Take out the old cabin air filter and replace it with a new one.
Ensure that the filter is installed in the correct orientation.
