Solution

1. Preparation

Tools Required: Safety glasses, gloves, OBD-II scanner, refrigerant pressure gauge.
Disconnect the battery to ensure safety while working on electrical components.

2. Recharge Refrigerant

Sub-steps:
1. Connect the refrigerant pressure gauge to the low-pressure service port.
2. Check the refrigerant level; if low, proceed to recharge.
3. Use the appropriate refrigerant type (R-134a or R-1234yf as per the system specs).
4. Start the engine and turn the AC to maximum settings.
5. Add refrigerant until the pressure reaches the manufacturer-specified level.

3. Repair or Replace Components

Sub-steps:
1. If the AC compressor is not engaging, check its electrical connections and fuses.
2. If damaged, replace the AC compressor:
  - Remove the drive belt by loosening the tensioner.
  - Disconnect electrical connectors and refrigerant lines (ensure the system is properly evacuated first).
  - Install the new compressor and reconnect all lines and connectors.
  - Reinstall the drive belt.
3. If the cabin air filter is blocked, replace it:
  - Access the cabin air filter compartment (usually under the dashboard).
  - Remove the old filter and install the new one.

4. Test the System

Sub-steps:
1. Reconnect the battery.
2. Start the vehicle and turn on the AC to the maximum setting.
3. Monitor the system for leaks and ensure the compressor engages correctly.
