You rely on your car's AC on a regular basis to ensure that you stay comfortable while on the road in any weather condition. Unfortunately, car AC problems are quite common and driving through hot weather without properly functioning AC can be quite uncomfortable. If your car's AC is experiencing issues, the good news is that you there are some DIY troubleshooting tips you can follow to figure out and resolve the problem as soon as possible.

Air Conditioning Leaks

Among the most common issues with car AC systems are leaks; your car's air conditioning systems is configurated much like a refrigerator, with many hoses and valves. Therefore, there's a lot that can go wrong in terms of fluid leaks. The first thing you should do if your car's AC is malfunctioning, then, is to use a leak detection kit, which you can find at most auto supply stores. Such a system uses a dye to alert you to leaks within your car's AC system. If you detect a leak with a kit, bring it into an auto repair shop. It should be a quick and relatively inexpensive fix.

Compressor Problems

Another possible problem to consider when it comes to your car's AC is that of compressor issues; if this happens, then the bad news is that replacing or repairing your car's compressor can be quite pricey. Most often, if your compressor isn't working, then you won't hear anything when you turn your AC on, even if it's on full-blast. You can use a voltmeter to determine whether or not there is any voltage running through the compressor itself; if not, then it might be time for a replacement.

Clogs and Restrictions

Finally, don't fail to consider the possibility that some kind of clog could be causing your car's AC problems. Over time, leaves, dirt, and even insects can clog up your car's cabin air filter, so you might want to consider replacing said filter if you haven't done so in the past year or so. You can also check the AC condenser to ensure that there isn't any debris layering on top of it, which can easily be removed by hand.

Dealing with a malfunctioning AC system can be a real pain, but the good news is that you can often diagnose the problem yourself. Just be sure to keep these tips in mind as you determine what's wrong with your AC.
