Why Is My Car Air Conditioning Not Working?

June 26, 2017

Is your car’s air conditioning not working? Is it blowing warm air instead of cold? Is it not blowing any air at all? There are a few reasons why your car’s air conditioner may not be working and in this article we will explain these issues and the best course of action to try and fix them.

Why Is My Car Air Conditioning Not Working?

Low Freon Levels

The first reason a vehicle’s air conditioning would stop working, and typically the most common, is that the A/C system is low on Freon. Freon is the refrigerant in your A/C system which cools the air; no Freon means no cold air.

Sometimes, Freon dissipates slowly over the lifetime of a car; in other cases there will be a more serious leak. Leaking Freon can cause extensive damage to the rest of your A/C system if left unchecked. For this reason, it’s suggested you bring your vehicle into your local Annapolis auto repair center in order to diagnose and repair the leak.

Compressor not Engaged

Another possible reason your car’s air conditioning isn’t working could be the A/C compressor is not engaging. This can happen if there is an electrical problem in the compressor’s circuitry or clutch; it could even be caused by low Freon or your vehicle overheating.

These days cars are all monitored and controlled by computers. Guess which system is usually one of the first that gets switched off when the computer thinks there’s an engine problem? Yes, the air conditioning system. This type of fix requires the care of an experienced Annapolis, MD auto mechanic, so be sure to contact one immediately.

Blend Air Door Issues

Your air conditioning might also have a problem with a ventilation system component called the “blend air door”. The blend air door is inside your ventilation system and its job is to block hot air from the engine and switch air flow to draw in cold air from the A/C system.

If this blend air door gets stuck or doesn’t function properly it will keep drawing heat from your car’s engine and mix it with the cold air from the A/C unit. Fixing this issue will require the help of a professional mechanic and auto repair shop.

Fan not Functioning

Now if you can feel the air is cold, but it’s just not blowing air very hard, the issue could be that your A/C unit’s fan isn’t working. This issue could require a whole new fan or it might be as easy as changing a wire or fuse. You’ll need to bring your car into an Annapolis mechanic because this fix may involve taking open your car’s dashboard.
