Solution
1. Preparation
  • Tools Required: OBD-II scanner, manifold gauge set, socket set, multimeter, safety goggles, gloves.
  • Safety Warning: Disconnect the battery before working on electrical components.
2. Check and Recharge Refrigerant
  1. Connect Manifold Gauge: Attach the manifold gauge set to the low and high-pressure service ports of the AC system.
  2. Check Pressure Readings: Evaluate the pressure readings. If the low side is below the recommended levels (typically below 30 psi), the system may need refrigerant.
  3. Add Refrigerant: If low, connect the refrigerant can to the low-pressure port and add refrigerant according to manufacturer specifications. Monitor the gauge to avoid overcharging.
  4. Disconnect Gauges: Once the correct level is reached, remove the manifold gauges and replace the service port caps securely.
3. Replace Faulty Components
  1. Inspect and Replace the AC Compressor: If the compressor is not engaging or damaged, remove the serpentine belt and disconnect the AC lines. Replace the compressor with a new one, ensuring proper alignment.
  2. Check and Replace Fuses/Relays: If any fuses or relays were found faulty during diagnostics, replace them with new ones of the same rating.
