What are the reasons why the BYD Qin's air conditioner only blows air but does not cool?

Reasons why the air conditioner only blows air but does not cool: 1. Lack of refrigerant: This leads to insufficient refrigerant in the air conditioning system pipeline, reduced pressure, and decreased heat absorption, resulting in the feeling of only blowing air without cooling. In this case, observe through the sight glass above the dryer. During normal operation of the air conditioner, if there are continuous slow bubbles in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping occurs, it means the refrigerant is severely insufficient. 2. Excessive refrigerant: There is a required proportion of refrigerant in the air conditioning system. If the proportion is too high, it will affect heat dissipation. Similarly, if too much cooling oil is added during maintenance, it will also reduce the heat dissipation of the refrigeration system. 3. Aging or loose belt: A loose drive belt of the car air conditioning compressor can cause slippage during operation, leading to reduced transmission efficiency, decreased compressor speed, and reduced refrigerant delivery, resulting in the air conditioner not cooling.
Driving my BYD Qin on the road, I found the AC only blows air without cooling, which is really annoying! I've encountered similar situations before, usually due to insufficient refrigerant, especially in older cars where Freon might have leaked, preventing the compressor from starting. Also, first check the AC settings to make sure it's not set to ventilation mode without cooling. If these aren't the issue, it might be a blown fuse—locate the AC section in the fuse box and try replacing it with a new one. In my own car, it was a fuse problem, and everything worked fine after fixing it. Remember, in the summer heat, don't tough it out—quickly find a repair shop to check the cooling system, safety first. Also, pay attention to cleaning the AC filter during regular maintenance to extend its lifespan.
