What should I do if the car compressor pipe freezes?

Check the temperature sensor and the regulating valve, and replace whichever is faulty. Many cases of frost formation in air conditioning pipelines are caused by a stuck expansion valve. Replacing it can resolve the issue. Check the refrigerant level in the air conditioning system. If it is insufficient, replenish the refrigerant according to the standard.
I've encountered a similar issue before. When the compressor pipes freeze, you must never suddenly step on the accelerator and turn on the AC. My habit is to immediately turn off the cooling system and let the engine idle for about ten minutes, allowing the ice to melt naturally. Then, check if the refrigerant is low or if there's a leak—you might need to top it up. When driving normally, avoid always setting the AC to high cooling. In summer, don’t set the temperature too low, as this can easily cause freezing and damage the pipes. Have a mechanic check if the expansion valve or filter is clogged, as these are common causes. Regular AC maintenance can save you a lot of trouble. Last time, I delayed repairs for a few days, and the compressor ended up failing, resulting in even greater losses. Safety first—if you notice a problem, turn off the AC immediately.
I often encounter frozen pipes while driving, mostly due to issues with the cooling system, especially under high load during hot weather. Remember to turn off the engine and let it sit for a few minutes—don't force it to start. Only use the air conditioning after the ice has melted. For a quick fix, check if the vehicle's radiator is dirty or clogged; cleaning it might help. Insufficient refrigerant is also a common culprit. I usually replace the filter during maintenance to ensure smooth operation. New drivers shouldn't panic—it's not a major issue, but delaying repairs could damage components and cost more to fix. In emergencies, stop and check if the pressure is normal. For daily driving, setting the air conditioning to a moderate temperature will make it last longer.
