Solution

1. Preparation

Tools Required: OBD-II scanner, refrigerant gauge, multimeter, socket set.
Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before servicing the AC.

2. Recharge the AC System

Locate the Low-Pressure Service Port:
- Find the low-pressure service port on the AC line (usually marked with a blue cap).
Connect Refrigerant Gauge:
- Attach the refrigerant gauge to the low-pressure service port.
- Ensure the gauge is calibrated and functioning properly.
Add Refrigerant:
- If the pressure is low, follow the manufacturer's specifications to add the correct type of refrigerant (typically R-134a or R-1234yf).
- Monitor the pressure gauge as you add refrigerant until it reaches the correct level.
- Ensure the AC is running while adding refrigerant for more accurate readings.

3. Repair or Replace Faulty Components

Inspect and Replace the AC Compressor:
- If the compressor is not engaging, check the clutch. If faulty, replace the compressor.
- Remove the serpentine belt and unbolt the compressor from its mount.
- Disconnect electrical connectors and refrigerant lines (recover refrigerant safely if necessary).
- Install the new compressor and reconnect all lines and electrical connections.
Replace the Cabin Air Filter:
- Open the glove compartment and remove the filter cover.
- Take out the old cabin air filter and replace it with a new one.

4. System Check

Run the AC: After repairs, run the AC system to ensure proper function and check for any leaks.
