Avio's air conditioner will still have refrigeration when it is first turned on, but it will not blow out at all after a while. What is the reason?

There are still a few months to accompany my little love, and it will be her fourth birthday soon. It's really hot in summer now, and air conditioners always have such problems. Please give me some guidance. There are still a few months to accompany my little love, and it will be her fourth birthday soon. It's really hot in summer now, and air conditioners always have such problems. Please give me some guidance. Some time ago, after the car started, it idled in place and turned on the air conditioner, which was not only not cold, but also hotter than outside the car. When I went to the repair shop, the engineer found that the air conditioner compressor didn't work at idle speed, so I didn't cool it, but I cooled it directly when I gave the oil. I think the throttle is dirty, and the air conditioner works normally after cleaning. I'm the same as you, but it's not as cold as before with Krugman's sensor! Now summer is a kind of pain! What should I do? I tried the same situation as you. When the air volume decreases, you turn on the range hood to see if there is a layer of ice on the air conditioning pipe. If so, there was something wrong with the sensor, and then I changed it to a Cruze one. Check the compressor to see if it is damaged. My compressor was scrapped not long after I bought it, and the air conditioner couldn't cool it. I went to 4S to check that the compressor was scrapped and directly applied for a new one. Try changing Cruze's temperature sensor first. If not, it will be more troublesome. Some brothers in the forum added resistors to solve their own problems. It is useless to replace the sensor and expansion valve. This is how I made the compressor. See if there is any refrigerant. Otherwise, change the temperature sensor of Cruze air conditioner and check it first. Check your coolant quickly. Maybe it has bottomed out. I've been in a friend's car before. At first, the air conditioning effect was very good, but later it gradually failed. Finally, the cylinder gasket was smashed and the car automatically turned off at high speed. This is a rip-off for waiting for someone else's high-speed emergency in the middle of nowhere. If you are satisfied, please adopt it. Thank you @20 19.
