1 Answers
High low pressure in car air conditioning is most likely caused by a malfunction or damage to the air conditioning expansion valve. Below are detailed explanations regarding high low pressure in car air conditioning: 1. Solution: The solution for high low pressure and normal high pressure in car air conditioning is quite simple. You only need to remove the air conditioning expansion valve and check whether it is functioning properly. If it is indeed faulty or damaged, simply replace it. 2. Precautions: Since the expansion valve in the car air conditioning system is located on the firewall side of the vehicle, it is quite inconvenient to remove. Additionally, temporary recovery of the refrigerant is required, which involves significant work. Therefore, it is recommended that car owners visit a 4S shop for this task, as attempting to do it themselves may lead to adverse effects.
