Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent any electrical shorts.
Wear safety goggles and gloves for protection.

2. Recharge the AC System

Tools Required: AC refrigerant gauge, refrigerant canister.
Check the refrigerant level using the gauge; if low, proceed to recharge.
Attach the refrigerant canister to the low-pressure service port.
Follow canister instructions to add refrigerant until the gauge indicates proper level (typically around 30-40 psi for most systems).
Disconnect the refrigerant canister and recheck the system pressure.

3. Inspect and Replace Compressor

Tools Required: Socket set, torque wrench, AC compressor replacement.
Remove the serpentine belt by loosening the tensioner pulley.
Disconnect the electrical connector from the AC compressor.
Disconnect the refrigerant lines from the compressor (ensure system is properly evacuated).
Remove the old compressor and install the new one, ensuring all gaskets and seals are replaced.
Reconnect refrigerant lines and electrical connector.
Reinstall the serpentine belt.

4. Replace Cabin Air Filter

Tools Required: None required.
Locate the cabin air filter compartment (typically under the glove box).
Remove the cover and take out the old filter.
Install the new cabin air filter in the correct orientation.
Reattach the cover.

5. Test the AC System

Reconnect the battery.
Start the engine and turn on the AC to the coldest setting.
Monitor for proper cooling and check for unusual noises.
