In the summer, you’re probably using your car’s air conditioner often. If it suddenly breaks down or doesn’t work as expected, it may mean you require auto repairs. There are many different reasons why an AC may stop working, but understanding some of the common causes may help you diagnose the issue before you even arrive at the auto shop. To help you do this, here are a few of the problems that sometimes result in AC failure.

Causes of Air Conditioning Malfunctions

1. Refrigerant Leaks

If your system is leaking refrigerant, it may stop working. Without this cooling fluid, the unit can’t generate the cold air it needs, simply blowing out warm air instead. If you notice puddles of red or green liquid beneath your car after you park, you may have a leak. Hissing or clicking sounds may mean that the condenser is cycling on and off repeatedly, which also indicates a leak.

2. Electrical Issues

There are a variety of electrical issues that may cause the AC to stop working, particularly in newer vehicles. Sometimes the wiring is faulty or becomes frayed, which may warrant a replacement. It could also be a malfunction in the AC control module, which passes instructions to the system through electrical charges. When you take the vehicle in for auto repairs, the technician will test the system with an electrical diagnosis device to pinpoint the problem.

3. Mechanical Failure

Since a vehicle’s air conditioner relies on multiple moving pieces, a mechanical issue may cause it to stop. If the compressor breaks down, it’s not able to move the refrigerant through the system, which results in warm air coming out. If no air is blowing, it may be an issue with the motor. The doors that stop or allow air to flow through the vents may also become jammed with debris, preventing cool air from entering the cabin.
