Solution

1. Preparation

Tools Required: OBD-II scanner, refrigerant gauge, socket set, screwdrivers, multimeter.
Disconnect the vehicle's battery to ensure safety while working on the AC system.

2. Replace Cabin Air Filter

Locate the cabin air filter housing, usually situated behind the glove compartment.
Remove the screws or clips securing the glove compartment and lower it to access the filter.
Take out the old cabin air filter and install the new one, ensuring it is properly seated.

3. Recharge Refrigerant

Attach the refrigerant gauge to the low-pressure service port of the AC system.
Check the pressure readings; if low, proceed to recharge the system.
Use a refrigerant canister and connect it to the gauge. Follow the manufacturer's instructions to add refrigerant until the appropriate level is achieved.
Disconnect the gauge and securely close the service port.

4. Check and Replace AC Compressor

Inspect the AC compressor visually for cracks or leaks.
If damaged, remove the AC compressor by disconnecting the electrical connector and the refrigerant lines (ensure refrigerant is properly recovered).
Install the new AC compressor, ensuring all connections are tight and the correct torque specifications are followed.

5. Inspect AC System Components

Check the AC condenser and evaporator for any debris or blockages.
Clean or replace any components that are obstructed. Ensure the condenser is free from dirt and debris for optimal airflow.
