Solution

1. Preparation

Tools Required: OBD-II scanner, refrigerant gauge, basic hand tools (socket set, screwdrivers), multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts during repairs.

2. Check and Recharge Refrigerant

Sub-steps:
1. Connect the refrigerant gauge to the low-pressure service port.
2. Check the pressure readings: if low, proceed to recharge.
3. Add the appropriate refrigerant (R-134a or R-1234yf, depending on the system specification).
4. Monitor pressure while adding refrigerant to avoid overcharging.

3. Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter compartment (usually behind the glove box).
2. Remove the retention clips or screws and pull out the old filter.
3. Install the new cabin air filter, ensuring it is oriented correctly.
4. Reattach the compartment cover.

4. Repair or Replace AC Compressor (if faulty)

Sub-steps:
1. Disconnect the electrical connector and refrigerant lines from the AC compressor.
2. Remove mounting bolts securing the compressor.
3. Install the new compressor and tighten bolts to manufacturer specifications (typically around 15-20 ft-lbs).
4. Reconnect refrigerant lines and electrical connectors.

5. Test and Recheck System

Sub-steps:
1. Reconnect the battery and start the engine.
2. Turn on the AC and check if the compressor engages and cold air is produced.
3. Monitor system pressures to ensure they are within normal operating ranges.
