Solution
1. Preparation
  • Tools Required: OBD-II scanner, manifold gauge set, socket set, screwdriver set, multimeter.
  • Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before starting.
2. Check and Recharge Refrigerant
  1. Connect the manifold gauge set to the AC service ports.
  2. Check the pressure readings; compare them against manufacturer's specifications.
  3. If low, recover any remaining refrigerant using a refrigerant recovery machine.
  4. Attach the refrigerant can to the low-pressure side and add refrigerant until the desired level is reached.
  5. Monitor the pressures during the recharge process to avoid overfilling.
3. AC Compressor Inspection
  1. Visually inspect the AC compressor for signs of wear or leaks.
  2. If the compressor does not engage, use a multimeter to test the voltage at the compressor clutch connector.
  3. If there is voltage but the clutch does not engage, replace the AC compressor.
  4. If there is no voltage, trace back to the relay and check for continuity; replace the relay if faulty.
4. Replace Cabin Air Filter
  1. Locate the cabin air filter access panel, usually behind the glove compartment.
  2. Remove the panel by unscrewing any screws or unclipping.
  3. Take out the old cabin air filter and clean the housing area.
  4. Install a new cabin air filter, ensuring it is oriented correctly for airflow.
