Solution
1. Preparation
  • Gather tools: OBD-II scanner, refrigerant gauge, multimeter, socket set, and safety glasses.
  • Ensure the vehicle is parked on a level surface with the engine off.
  • Disconnect the negative battery terminal to prevent electrical shock.
2. Addressing Refrigerant Issues
  1. Check and Recharge Refrigerant
    • Attach the refrigerant gauge to the low-pressure service port.
    • Check the pressure readings against manufacturer specifications.
    • If low, add the appropriate type of refrigerant (R-134a or R-1234yf as specified).
    • Monitor for leaks during the recharge process.
3. Inspecting and Replacing Components
  1. AC Compressor Clutch Inspection

    • Reconnect the negative battery terminal.
    • Start the engine and turn on the AC to the maximum setting.
    • Observe the AC compressor clutch; if it does not engage, test the clutch coil with a multimeter.
    • If faulty, replace the AC compressor.
  2. Cabin Air Filter Replacement

    • Locate the cabin air filter access panel (usually behind the glove compartment).
    • Remove the old filter and inspect for dirt and debris.
    • Install a new OEM replacement filter, ensuring proper orientation.
4. Electrical System Check
  1. Relay and Fuse Inspection
    • Locate the fuse box and check the AC relay and fuses for continuity using a multimeter.
    • Replace any blown fuses or faulty relays with OEM parts to ensure proper operation.
