What happens when you turn on the air conditioner in your car? Do you get a nice rush of cool air? Or if the air does come out, is it hot or foul smelling? How is your car air conditioner working? It can be very frustrating when you get into your car, expecting a cooling breeze, and instead you get sputters of hot air. It doesn’t take a rocket scientist to recognize that your car air conditioner isn’t working. With the summer months almost here, a working air conditioner in your car is practically a necessity and in this day and age, we don’t have to suffer from the heat while we travel. The following tips should help you decide where the problem may lie and what you might do to fix it.
Your car air conditioner is made up of several parts: a compressor, a condenser, an evaporator, and several valves, fittings and hoses. A fairly common reason for your car’s air conditioner to stop working is a lack of refrigerant. Pressure gauges can be used to determine if your air conditioner needs a charge, or if your system may be losing refrigerant due to a leak. Possibly a cracked hose, a pinhole in the condenser, or a leaky compressor. A special dye can be added to your system that will help to locate a leak.
While the car is running, turn on the air conditioner and listen for the clutch of your compressor to engage. If it does not engage or if it engages and disengages rapidly, you could have a blown fuse or may need to replace the clutch.
If your car’s air conditioner is noisy, make sure that all mounting bolts connected to your air conditioning system are tight. This should help eliminate any rattling or other noises.
If your system has intermittent cooling, it may be freezing up. Air and moisture in the system can cause this to happen. You should use a vacuum pump to rid the system of moisture and air.
If you have a mold or mildew smell when you use your air conditioner, condensation has probably become trapped within one or more of the areas of the air conditioning system. There is a service available to remove this mold and mildew from your system.
When all else fails, take your car to your auto technician and have your cooling system serviced. Your auto technician will be able to diagnose any problems and make the necessary repairs to make your summer driving cool, clean and comfortable.
