Solution
1. Preparation
  • Gather tools: A/C manifold gauge set, OBD-II scanner, basic hand tools, and safety goggles.
  • Ensure the vehicle is parked on a level surface with the engine off and cooled down.
2. Check Refrigerant Level
  • Connect the manifold gauge set to the A/C service ports (high and low).
  • Start the vehicle and turn on the A/C to the maximum setting.
  • Read the pressure readings on the gauges:
    • Low side pressure should be between 25-45 psi.
    • High side pressure should be between 150-250 psi depending on ambient temperature.
  • If the refrigerant level is low, proceed to the next step.
3. Recharge A/C System
  • If low refrigerant is confirmed, add the appropriate type of refrigerant (typically R-134a or R-1234yf, depending on the system).
  • Follow the manufacturer’s specifications for the amount of refrigerant to add.
  • Monitor the pressure readings while recharging to avoid overfilling.
4. Inspect and Replace Components
  • If the system still does not cool, inspect the A/C compressor:
    • Check for any signs of wear or damage.
    • If the compressor does not engage, test the electrical connections and fuses.
  • Replace the A/C compressor if defective.
  • Change the cabin air filter if it appears clogged.
5. Final Checks
  • After repairs, perform a leak test using a leak detector or soap solution.
  • Run the A/C system and monitor for any leaks.
  • Ensure proper operation of the A/C by checking airflow and temperature from the vents.
