my Skoda Octavia NFL (2020-Present) AC is not blowing cold air, what could be wrong?

Solution

1. Preparation

• Tools Required: OBD-II scanner, refrigerant gauge, basic socket set, multimeter.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the battery before working on electrical components.

2. Check Refrigerant Level

• Sub-steps:
  1. Connect the refrigerant gauge to the low-pressure service port.
  2. Check the gauge reading; it should be within the manufacturer's specifications (typically 30-40 psi).
  3. If low, proceed to recharge the system.

3. Recharge AC System

• Sub-steps:
  1. Use a refrigerant can to recharge the system through the low-pressure port.
  2. Start the engine and the AC system, and monitor the pressure gauge to ensure it stabilizes within the correct range.
  3. Check for leaks at the service port after recharging.

4. Replace AC Compressor (if necessary)

• Sub-steps:
  1. Disconnect the battery.
  2. Remove the drive belt from the AC compressor.
  3. Unplug the electrical connector from the AC compressor.
  4. Remove the mounting bolts securing the compressor and take it out.
  5. Install the new compressor, ensuring proper alignment and torque specifications (typically 20-25 Nm).
  6. Reconnect all electrical connections and the drive belt.
