Unfortunately, problems with car air conditioning are very common. If you have an air conditioner in your home or office, then you probably know that they are prone to experiencing technical difficulties. While you may not experience any problems with the air conditioning in late model cars, it is very likely that you will if you have an older car. For the most part, many of the common problems that will arise with your car's AC system you can fix yourself, but it is always best to enlist the help of a mechanic when needed. If you are in need of any car parts or supplies, check out stores like Auto Barn and Auto Parts 123. Here are some common problems:
No Lubricant or Refrigerant
Having not enough or no lubricant or refrigerant in your vehicle's system is one of the most, if not the most, common problems with car air conditioning. The compressor in your vehicle needs to kick on for you to get cold air. If you are low on lubricant or refrigerant, the compressor will not turn on, which means your AC won't function properly. The lubricant or refrigerant in your vehicle can dry out or leak sometimes, so it is something that you should check on a monthly basis. If you need to replenish the lubricant or refrigerant, refer to your owner's manual to find out what type is needed.
Many people do not realize that there is an electrical component to the air conditioning system in their car. If you find that you are not getting any cold air and you are not running low on lubricant or refrigerant, the next thing that you should check is the fuse box in your vehicle. The electrical wiring that is associated with your AC system allows you to control the temperature, runs the blower fans and much more. Replacing a blown fuse should only take five minutes of your time. However, you may want to bring your vehicle into a mechanic so it can be determined if an electrical fault is causing the fuse to blow. If that is the case, you can replace the fuse, but it will simply blow again in due time.
Intermittent Cold Air
Receiving intermittent cold air is a real pain in the you know what, especially during the summer months when you need that cold air the most. Generally speaking, if you find that you are receiving cold air, but it randomly switches over to hot air, it means that the evaporator or tube in your AC system is freezing up. When that happens, the refrigerant cannot travel through the system, which means the compressor can't produce cold air. Unless you have an AC vacuum pump, you will need to visit a mechanic for this issue. A few other causes of intermittent cold air could be a bad temperature sensor, a faulty controller module and a faulty low-pressure cutout switch.
