Solution

1. Preparation

Gather tools such as an OBD-II scanner, multimeter, refrigerant gauge set, and basic socket set.
Ensure the vehicle is parked on a level surface with the engine off. Disconnect the battery for safety.

2. Recharge Refrigerant

Tools Required: Refrigerant gauge set, refrigerant canister, safety goggles, gloves.
Connect the gauge set to the low and high-pressure service ports.
Check the pressure readings; if low, proceed to recharge.
Following manufacturer specifications, add refrigerant until optimal pressure is achieved. Monitor the gauge continuously to avoid overcharging.
Disconnect the gauge set and securely cap the service ports.

3. Inspect and Replace A/C Compressor

Tools Required: Socket set, torque wrench, A/C compressor removal tool.
Remove the serpentine belt by loosening the tensioner.
Disconnect electrical connectors and refrigerant lines from the A/C compressor.
Remove mounting bolts and carefully extract the compressor.
Install the new compressor by reversing the removal steps, ensuring all connections are secure.

4. Replace Cabin Air Filter

Tools Required: None required, but a flat-head screwdriver may help.
Locate the cabin air filter compartment, usually behind the glove box.
Remove the glove box or cover to access the filter.
Take out the old filter, clean the compartment, and install a new filter in the correct orientation.

5. Test A/C System

Reconnect the battery and start the engine.
Turn on the A/C to check if the system is functioning and blowing cold air.
Monitor the A/C operation for noise and ensure proper airflow.
