Solution

1. Preparation

Tools required: A/C manifold gauge set, basic socket set, multimeter, safety glasses, gloves.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Recharge A/C System

Locate the low-pressure port on the A/C system (usually on the larger diameter pipe).
Attach the manifold gauge set to the low-pressure port.
Check refrigerant levels: If low, proceed to recharge.
Connect the refrigerant canister to the manifold gauge and open the valve to allow refrigerant in, following the manufacturer’s recommendations for the amount of refrigerant.
Monitor the gauge while recharging to reach the correct pressure.

3. Inspect and Replace Components

Inspect the A/C compressor:
- Check the electrical connections and ensure the compressor clutch is engaging.
- If the compressor is not engaging, test the electrical circuit with a multimeter.
Replace the A/C compressor if faulty:
- Remove the serpentine belt.
- Disconnect the A/C lines and electrical connectors.
- Remove mounting bolts and take out the compressor.
- Install the new compressor in reverse order of removal.

4. Replace the Cabin Air Filter

Locate the cabin air filter housing (usually behind the glove box).
Remove the glove box for access, if necessary.
Take out the old cabin air filter and inspect for blockages.
Install a new cabin air filter in the correct orientation.

5. Test the System

Reconnect the battery and start the vehicle.
Turn on the A/C system to the maximum setting and monitor for cold air.
Check A/C pressures again with the manifold gauge to ensure they are in the proper range.
