Solution

1. Preparation

Tools Required: Safety goggles, gloves, socket set, OBD-II scanner, manifold gauge set, refrigerant refill kit.
Disconnect the vehicle battery for safety.
Allow the engine to cool down before starting work on the AC system.

2. Check and Recharge Refrigerant

Sub-steps:
1. Connect the manifold gauge set to the low and high-pressure ports of the AC system.
2. Start the vehicle and turn on the AC to the maximum setting.
3. Observe the pressure readings on the gauges.
  - If pressures are low, proceed to recharge the system.
4. Follow the instructions on the refrigerant refill kit to add the appropriate amount of refrigerant.
5. Monitor the system to ensure pressures stabilize within the manufacturer’s specifications.

3. Repair or Replace AC Components

Sub-steps:
1. If the compressor is not engaging, check the electrical connections and relay function.
2. If the compressor is faulty, remove it by disconnecting the electrical connector and removing the mounting bolts.
3. Install the new AC compressor, tightening the bolts to the manufacturer's specifications (typically around 15-20 ft-lbs).
4. Reconnect the electrical connector and check for proper operation.

4. Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter housing, usually found behind the glove box.
2. Remove the glove box if necessary to access the filter.
3. Remove the old filter and install the new one, ensuring correct airflow direction.
4. Reassemble the glove box.
