What is the reason why the Changan Eado air conditioner sometimes does not cool?

The reasons why the Changan Eado air conditioner sometimes does not cool are: 1. The condenser is too dirty; 2. Damage to the air conditioning compressor, throttle valve, or expansion valve; 3. Belt aging or looseness; 4. Water in the pipeline. The Changan Eado is a compact car with body dimensions of 4730mm in length, 1820mm in width, 1505mm in height, and a wheelbase of 2700mm. The Changan Eado is equipped with a 1.4L turbocharged engine, with a maximum power of 116kW, a maximum power speed of 6000rpm per minute, and a maximum torque of 260Nm, paired with a 7-speed dual-clutch transmission.
I've been driving the Changan Eado for many years and have encountered the annoying issue of intermittent air conditioning problems. Here's my experience sharing. The most common cause might be refrigerant leakage, where slow seepage leads to insufficient pressure, making the issue more noticeable in hot weather; it could also be poor contact in the compressor clutch, causing unstable current during startup and shutdown, resulting in intermittent operation. A clogged air conditioning filter can also block airflow, leading to poor cooling; another possibility is a dirty evaporator freezing up and blocking the passage. I recommend first trying to replace the filter yourself (located under the glove box) and cleaning it thoroughly with a vacuum cleaner; if that doesn't work, quickly take it to a repair shop to check the pressure or refill the refrigerant—don't delay, as stalling on the road can be more dangerous. During maintenance, pay more attention to cleaning the air conditioning system; regular upkeep can save a lot of trouble.
In my daily car repair work, I often encounter cases where the Changan Eado's air conditioning has issues. The intermittent cooling failures mostly stem from a few common points. Unstable pressure in the refrigeration system, such as slight pipeline leaks or uneven refrigerant charging; poor compressor performance, with aging capacitors or clutch slippage causing intermittent engagement; non-functioning cooling fans or clogged condensers affecting heat dissipation efficiency. During inspection, first use simple tools to measure airflow, then check for loose electrical connections. I advise car owners not to disassemble components themselves randomly—first try switching between internal and external air circulation modes. If that doesn't work, seek professional technicians to check for leaks or replace components, preventing minor issues from escalating into major problems that could affect summer travel safety.
As a newbie who has only been driving the Eado for half a year, I got really nervous when the AC sometimes worked and sometimes didn't, so I rushed to get it fixed. The technician said it could be due to poor contact in the compressor circuit, rusted or worn-out connectors; the AC filter not being replaced for too long, causing dust blockage; or a faulty temperature sensor misjudging the cabin temperature, leading to intermittent failure. In my case, it was the sensor issue, and it worked fine after replacement. A reminder to everyone: if you encounter this situation, don't panic, safely pull over and open the windows for ventilation; regularly clean the filter and remind the technician to check AC components during maintenance to prevent similar incidents.
