Solution

1. Preparation

Required Tools: OBD-II scanner, manifold gauge set, multimeter, basic hand tools (screwdrivers, wrenches).
Safety Warning: Disconnect the battery before working on electrical systems; ensure the engine is cool before performing repairs.

2. Refrigerant Recharge

Connect Manifold Gauges: Attach the high and low-pressure hoses to the AC service ports.
Check Pressure Readings: Assess the pressure readings to confirm refrigerant levels.
Evacuate System (if necessary): Use a vacuum pump to evacuate the system if it is found to be low on refrigerant.
Recharge with Refrigerant: Add the appropriate type and amount of refrigerant according to the manufacturer specifications.

3. Component Replacement

Remove the AC Compressor:
- Disconnect electrical connectors and hoses from the compressor.
- Unbolt the compressor from its mounting bracket.
- Replace with a new or refurbished compressor.
Replace the Cabin Air Filter:
- Access the cabin air filter housing (usually located behind the glove box).
- Remove the old filter and install the new one in the correct orientation.

4. Electrical Repair

Inspect and Repair Wiring: Examine and repair any damaged wiring or connectors that may affect AC operation.
Replace Fuses: If any fuses related to the AC system are blown, replace them with the appropriate amperage.
