Porsche Air Conditioning Not Blowing Cold or Warm Air?

[DiDonovan]

Detailed explanations and solutions for the reasons why Porsche air conditioning is not blowing cold or warm air are as follows: 1. Refrigeration malfunction: If the refrigeration suddenly stops working, the most likely cause is frost or ice formation on the evaporator, which affects the airflow circulation, resulting in reduced air volume. While driving, the compressor is driven at high speed by the engine, providing excellent cooling performance. As the cabin temperature gradually decreases, the evaporator has no heat to exchange, preventing the refrigerant from vaporizing and returning to the compressor. This leads to liquid compression, ice formation on the evaporator, and the antifreeze protection switch tripping, causing the refrigeration to stop. Solution: Check the radiator and fan, or appropriately reduce the refrigerant. 2. Compression malfunction: If the compressor runs at high speed with the engine for an extended period, the high pressure remains excessively high, causing the overload protection switch to trip. Solution: Replace the low-pressure hose and test the refrigeration after installation.
