How To Troubleshoot Porsche Air-Conditioning Problems

Warm air blowing from your Porsche’s air conditioner can seem like a living nightmare, especially when the sun is beating down on you in the summer months. Your car’s air conditioning system is comprised of many parts, including heat exchangers, a compressor, an expansion valve as well as refrigerant which means that when your air conditioner acts up, there could be a few things wrong. However, learning to diagnose common AC problems can help you get back into being cool as soon as possible. In this article, we are going to explore some of the most common problems and how they can be fixed.

Lack of Cold Air

If you are experiencing a lack of cold air from your AC vents, it could be due to your refrigerant leaking. Refrigerant is an important part of your air conditioning system as it helps cool down the vehicle. Without an adequate amount of refrigerant, other components in the system will not be able to function. Leakage can occur in many different parts of the system and since it is not easily detectable, you will need to bring your car to an automotive technician. They will add additional refrigerant as well as fluorescent leak tracer dye and use a blacklight to identify the leak so that they can repair the area causing the leak.

Lack of Air from Vents

This problem is not as simple as having no air and thus will require a knowledgeable technician to diagnose the possible causes. The technician will check for a bad relay or a blown fuse, if there’s any blocked air intake, damage to the blower motor or resistor, etc. They will replace the relay of the fuse first to see if it fixes the problem. If the issue persists, they might refer to an expert air conditioning technician for additional help.

The Air is Cool but Not Cold

This problem is usually caused by a lack of refrigerant. However, if there is a sufficient amount of refrigerant, it could also be caused by a failed clutch switch or a condenser that is blocked or faulty. Bring your car to a technician for these components to be tested and they can easily be replaced as necessary.

Air Conditioning Smells of Mildew

If you turn on the AC only to be hit with an unpleasant smell, it could be due to bacteria growing in the system. This happens with older AC or AC that are not frequently turned on. The air filters that collect dust, dirt, water, or other pollutants should be changed and if that does not solve the problem, an anti-bacterial solution could be added to rid the system of contaminants.
