In order to understand more about why your car’s air conditioner stops working, its important to identify the most frequent issues and why they happen.
What to do if your car AC is not blowing?
Depending on what kind of car you have, it should be a pretty simple fix. The problem sounds like it is with your blower motor, not your AC system. Hopefully, the blower motor simply blew a fuse. Find your fuse panel and check the fuse for the “blower motor” or “vent fan” or something like that.
Why is my air conditioner not blowing cool air?
When your air conditioning system isn’t blowing cool air, that is the first sign that you need auto AC repair. There are a couple of reasons why your AC isn’t blowing cool air and instead is blowing warm air. The first reason why your AC isn’t blowing cool air is because it needs a freon recharge.
When do you know something is wrong with your AC?
The first sign that tells you something is wrong, is when you turn on the AC but all you feel is warm air blowing out of the air vents. What could be the problem?
When do you Know Your air conditioner is not working?
If you turn the thermostat to “Cool” and absolutely nothing happens, please see Central AC Not Working At All. This information will also guide you through checking the air handler, clearing the condensate drain, and checking the outdoor compressor. If you can hear the AC running but it isn’t blowing air, please see Air Conditioner Not Blowing Air.
Why does my a / C stop blowing cold after 20 minutes?
It sounds like the compressor is supplying too much pressure and the metering orifice into the heat exchanger is freezing. Exactly when it stops working, pull over safely, pop the hood and find the aluminum bottle near the back of the engine compartment. It should be covered with condensation, but I’m guessing it’ll be iced over. helpful?

Why does my air conditioner Jam in my car?
This typically happens because of a phenomenon mechanics call the black death. Refrigerant breaks down inside your car’s compressor and causes the compressor internals to degrade and eventually jam. To avoid this, make sure you take your car in for an air conditioning system evaluation occasionally.

Why does the AC blow cold air when the car is moving?
My car has an automatic transmission. When the car is moving, versus stopped, there is more air flow over the condenser (the heat exchanger in front of the radiator) and that airflow is essential to system operation. To maintain airflow when the car is in stop and go traffic, or is completely stopped, condenser fans will come on automatically.

Why does the AC blow warm at idle?
Since the AC compressor is driven by the engine, it doesn’t pump as much refrigerant when you’re at a stop or driving slowly. If the system is low on refrigerant, it will show up as AC blows warm at idle and blows colder when the engine is running at higher RPMs. Get your system refrigerant level checked.
Why does my air conditioner leak when I turn it off?
If your system is low on refrigerant or has a dirty filter, the system may freeze up when it’s working. After you turn it off, the ice melts, causing it to leak water. Don’t risk water damage from your air conditioner leaking water on the floor or ceiling.

Most central air systems run relatively quiet. You may hear a “swoosh” as the unit turns on and cool air floods from the vents and into your home.
