Solution

1. Preparation

Gather tools: OBD-II scanner, refrigerant gauge, multimeter, socket set, and safety goggles.
Ensure the car is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Recharge the AC System

Sub-steps:
1. Connect the refrigerant gauge to the low-pressure service port.
2. Check the pressure readings against manufacturer specifications.
3. If low, attach the refrigerant can and follow the instructions to recharge the system slowly.
4. Monitor the pressure gauge to ensure it reaches the appropriate level.

3. Repair or Replace the AC Compressor

Sub-steps:
1. If the compressor is faulty, remove the drive belt by loosening the tensioner.
2. Disconnect the electrical connector from the AC compressor.
3. Remove the mounting bolts of the compressor and take it out.
4. Install the new compressor by reversing the removal steps, ensuring to torque bolts to manufacturer specifications.
5. Reconnect the electrical connector and reattach the drive belt.

4. Replace the Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter housing, usually behind the glove box.
2. Remove the glove box or access panel to reach the filter.
3. Take out the old filter and clean the housing.
4. Insert the new filter, ensuring it's oriented correctly according to airflow direction.

5. Test the AC System

Sub-steps:
1. Reconnect the battery and start the engine.
2. Turn on the AC to maximum cooling and check for proper operation.
3. Monitor the temperature at the vents to ensure it is blowing cold air.
