What is the reason for the air conditioning not cooling after the car passes through water?
2 Answers
It is likely that the compressor has malfunctioned and needs to be repaired promptly. Introduction: Automotive air conditioning refers to the air conditioning device installed in a car, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers. It significantly reduces driver fatigue and improves driving safety. Structure: Generally, it includes refrigeration devices, heating devices, and ventilation devices. This combined system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern automotive air conditioning system internationally.
Last time after my car went through water, the air conditioning wasn't cooling either. The mechanic later said it might be due to water entering the electrical system. The air conditioning control module is located near the chassis and is prone to short circuits after being submerged, causing signal disruptions that prevent the compressor from working. There was also the issue of blown fuses—my own fuse box was full of moisture at the time, with several fuses blackened. Additionally, it's a common problem for sensors to be corroded by accumulated water, preventing them from sending cooling commands. Actually, if you notice the AC isn't cooling, you should stop and check immediately—don't keep driving and risk burning out the computer board. If necessary, disconnect the battery to cut power and have the car towed to a repair shop for circuit inspection. After all, modern cars have many electronic components, and malfunctions after water exposure are quite common.
