No matter what time of year it is, every driver reaches for their AC dial. Your car AC not working is a big problem, especially on a hot Virginia day. If you’re in the area of Salem, VA, your GMC dealer can fix this problem for you. We’d like to tell you more about some possible AC issues we can fix.
Dripping Water in the Cabin
Air flows into your car, is cooled by the refrigerant in the AC, and then blown into your cabin. This process also produces water, and this water needs to be removed from your car. Your AC’s evaporator coil produces much of this water, and it collects in the evaporator heater box. A rubber drain pipe runs from this box to the outside of your car, and it’s used to drain the water.
This hose can become blocked by bacteria growth over the long winter months. This blockage will prevent water from draining out of your car. The water level in the heater box will increase and eventually overflow and drip on the passenger side floor. We can clear the blockage to fix the drainage problem. We’ll also clean the carpet with a cleaning solution to prevent mold growth.
The AC Air Doesn’t Get Cold
Your AC should produce cold air on demand according to the temperate you set on the dial. If you find that the air isn’t getting cold regardless of the temperature setting, your AC has a problem. The two main causes of this issue are a damaged condenser and a failed compressor. These two components are responsible for changing the refrigerant that cools the air between gas and liquid states.
The condenser turns refrigerant gas into a liquid and removes the heat in the process. The compressor condenses the liquid back into a gas for cooling the air. If either of these components fails, your AC won’t produce cold air. A third possible problem is you have a refrigerant leak which is preventing the air from chilling. Our technicians will examine your AC and repair the cause of the problem.
Leaking Refrigerant
Refrigerant is the gas that chills the air in your AC system. A lack of refrigerant can only be due to a leak somewhere in the system. You can’t see a refrigerant leak, as liquid refrigerant evaporates when in contact with the air.
We use a special identifier dye to trace the leak. This dye is fed into the system, and our technicians track its progress with a special monitor. Once they identify the hole in the system they’ll repair it
If your AC seems to be on the fritz, call us at Hart Motors GMC.
