How To Diagnose Your Car’s A/C Problems

How To Diagnose Your Cars AC Problems

During the summer, cars can get extremely hot, and often, rolling down the windows isn’t enough to keep things cool. The only thing that keeps it bearable is air conditioning. But what happens when it malfunctions? 

Although we hope it won’t happen to you, it’s still helpful to know how to diagnose common A/C problems in your vehicle. This gives you the option of either fixing it yourself or taking it to a repair shop for service. 

A/C is Inconsistent

There can be times when a problem comes and goes. You may be frustrated by mechanics telling you there is no problem at this time. For a mechanic to diagnose a problem, they must experience the problem when he or she examines the vehicle. It is necessary to recreate the issue so that they can diagnose and fix it.

There are several reasons why your air conditioner may sometimes run fine and fail at other times. One of the seals might be leaking or the fuse is blown. The compressor clutch or compressor might be the problem. Another possibility is that the system is clogged.

Check the Compressor

When the engine is running, switch the A/C to maximum cooling, set the fans high, and ensure the clutch is engaged on the compressor. It can be a sign of low refrigerant if the clutch engages and disengages every few seconds.

You might also see that when you engage the clutch, the low-side pressure will drop rapidly on your gauge, and then drop to a point of too-low pressure, then rise once the clutch is disengaged. Adding more refrigerant should steady the gauge, and the pressure should stay at recommended levels as long as the compressor is running.

Air Blows Out Less Strongly than Before

In some cases, you have cool air blowing out, but it isn’t blowing out as strongly as it used to. Despite cranking up the A/C to its highest setting, it might only seem like you have it on medium or low. Several issues can cause this. Often, it’s a simple matter of replacing a hose or seal or maybe a faulty fan is to blame. There is also a possibility that mildew can be the culprit.

Examine the Leaks

You may notice this happening all at once, or you may notice it gradually. However, the air isn’t as cool considering how strong the flow of air is. Leaks are the most common cause of this, but clogs and damaged parts, such as the condenser, blower, or compressor, can also be responsible. Leaks are usually easy to fix and don’t cost a lot of money. The system can be compromised and further damage is expected if the problem goes unaddressed for a long period of time.
