Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery for safety.
Ensure the vehicle is parked on a level surface.

2. Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant, safety goggles, gloves.
Locate the low-pressure service port of the AC system.
Connect the low side of the manifold gauge to the port.
Start the engine and turn the AC to the maximum setting.
Open the valve on the refrigerant canister and monitor the gauge until it reaches the appropriate level as specified in the owner's manual.
Disconnect the manifold gauge and replace the service port cap.

3. Replace Cabin Air Filter

Tools Required: Screwdriver (if applicable).
Locate the cabin air filter housing, typically behind the glove compartment.
Remove the screws or clips securing the housing.
Take out the old filter, noting the orientation for the new one.
Install the new cabin air filter, ensuring it is seated correctly.
Reassemble the housing and secure it back in place.

4. Inspect and Replace AC Compressor (if necessary)

Tools Required: Socket set, torque wrench, gasket sealant.
Remove the serpentine belt from the AC compressor.
Disconnect the electrical connector from the compressor.
Unbolt the AC compressor from its mount and remove it from the vehicle.
