It’s still warm enough here in Knoxville TN that you might need to run your car, truck, or utility vehicle’s air conditioner. If you have not had this system serviced within the last 30,000 miles, you may end up with hot air or no air blowing through the vents instead of cool and refreshing air. Fountain City Auto Clinic is going to list the common problems with automobile air conditioners below. We can inspect your vehicle’s AC system to determine the exact issue.
Damaged Condenser
Because of where the condenser is located, it is susceptible to damage. You will find the condenser behind the grille in front of the radiator. Unfortunately, this means the condenser is hit regularly by road debris. This cannot only damage the condenser but also clog it. When this happens, the condenser loses its functionality and you end up with hot air blowing through the vents.
Dead Compressor
If the compressor has died, this, too, will cause hot air to blow through the vents. The compressor is an air conditioning system part that needs to be run once a month to keep it in good shape. This might seem inconvenient in the winter, but running the AC for at least 15 minutes will ensure that your compressor operates the way it needs to in the heat of summer.
Low Refrigerant Levels
Another thing that will cause lukewarm or hot air to blow through the vents is low refrigerant levels. Your air conditioning system’s refrigerant is a gas that is converted to liquid and then cooled and converted back to gas. It can leak through the hose connectors when it is in its liquid form and it can evaporate overtime when it is in its gas form.
Malfunctioning Electrical System
A malfunctioning electrical system can also prevent your air conditioner from working properly. You may find that the AC does not turn on when you press the button on your dashboard. This is an indication that you have a problem with the air conditioning system’s wiring or a blown fuse.
Malfunctioning Fan
Finally, if the fan is not working correctly, you won’t have any air blowing through the vents. This is uncomfortable whether you want the air conditioner on or the heater. This can be due to a problem with the electrical system or a faulty fan. We can find out why the fan is not working and fix the problem.
