You’re stuck in traffic on a sweltering day and when you turn on the AC for relief, you get a blast of warm air! Well, you’re in good company, as almost every driver has experienced their car AC not working. Luckily, if you’re in Highland Park, MI, you have a friendly Dodge dealer who can fix it for you.
How your AC Works
Your car’s AC contains refrigerant, a chemical that in its gaseous state absorbs and holds heat, and in its liquid state it expels heat. A compressor forces the liquid refrigerant under pressure into a condenser. The expansion valve on the condenser turns the refrigerant into a cold gas. This gas then passes through an evaporator which absorbs the heat inside your vehicle.
As the refrigerant gas absorbs heat, a fan blows across the evaporator and chills the air released into your car’s cabin. A drier captures any moisture in the air, and the refrigerant is recirculated to the compressor to start the process again.
Why My AC Isn’t Working Now
There are five main reasons for AC failure, and our experienced technicians can repair all of them.
Electrical Issues
There are several possible causes of an electrical failure, including a blown fuse, a failed switch, or even a problem with the AC control module. Electrical issues are usually easy to diagnose and fix. If they are not repaired, however, they can lead to acid buildup and potentially more serious damage to your AC.
Leaking Refrigerant
Over time, rubber seals and hoses can wear and loosen. If this happens, refrigerant gas will leak out of the system and your AC will no longer work properly. In addition, moisture can mix with the refrigerant, and form an acid that can permanently damage your cooling system.
Compressor Problem
If the compressor fails, it will no longer circulate refrigerant. This is a fairly common problem and is usually caused by not engaging the AC over the cooler days of fall and winter. A second possible issue is that the switch inside the compressor may have become stuck in the “off” position.
Condenser Problem
The condenser depressurizes, cools, and liquifies humid air from the compressor. If it fails, however, you will notice your AC no longer works efficiently. Another potential problem is that the condenser can develop a leak due to age or damage.
Broken Cooling Fans
The cooling fans circulate cold air, but damage, a blown fuse or an electrical short may cause them to stop working. If that happens, your cooling system will fail. This is usually a simple problem to fix, as the broken parts are easily replaceable.
