Solution

1. Preparation

Tools Required: OBD-II scanner, A/C gauge set, basic hand tools.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before working on the A/C system.

2. Check and Recharge Refrigerant

Connect the A/C gauge set to the low and high-pressure ports.
Check the pressure readings; refer to the manufacturer's specifications for normal ranges.
If low, add refrigerant (R-134a) slowly through the low-pressure port until the correct pressure is achieved.
Monitor the system performance as refrigerant is added.

3. Inspect and Replace A/C Components

A/C Compressor
- Disconnect the electrical connector from the compressor.
- Remove the compressor mounting bolts using a socket set.
- Replace the compressor if it shows signs of wear or is not engaging.
- Reinstall the new compressor and reconnect the electrical connector.
A/C Condenser
- Inspect the condenser for debris or damage.
- If blocked, clean it carefully with compressed air or a soft brush.
- If damaged, disconnect the refrigerant lines and replace the condenser.
Cabin Air Filter
- Open the glove compartment and locate the cabin air filter housing.
- Remove the old filter and replace it with a new one, ensuring proper airflow direction.

4. Test A/C System

Reconnect the battery and start the vehicle.
Set the A/C to maximum cold and fan speed.
Verify that the A/C compressor engages and check the temperature of the air coming from the vents.
