Volkswagen A/C Parts Buyer's Guide

Many car owners are intimidated by the idea of maintaining and repairing the air conditioning system in their vehicle. There are times when A/C system maintenance should be left to the professionals. That’s not always the case, though. If you own a Volkswagen vehicle, you don’t always have to bring your car to a shop when there are issues with its A/C system. In some cases, you can maintain and repair the system yourself.

In this buyer’s guide, you’ll learn everything you need to know about repairing and maintaining your Volkswagen’s A/C system.

What Is The A/C Compressor And Why Is It Important?

Your Volkswagen's A/C system has many different components that work together. The A/C compressor is one of the most important parts to know about. This post explains what an A/C compressor is and why it’s important. To sum it up, the A/C compressor compresses refrigerant so that it can later expand as it moves through the HVAC system. An A/C compressor lasts about 10-15 years. So if you have an older vehicle, chances are you'll need to replace the A/C compressor someday.

What Is The A/C Pressure Switch And Why Is It Important?

The A/C pressure switch is another important part you should know about. It’s a small temperature-sensitive safety switch. Your Volkswagen has two pressure switches: one on the upper side of the A/C system and another one on the lower side. This part exists to switch off the compressor whenever the refrigerant pressure gets too high or too low. This helps protect the compressor from wear and damage.

When your Volkswagen’s A/C system starts having issues, don’t be so quick to bring your vehicle to a shop. You can try to troubleshoot the issue at home. Sometimes the issue will turn out to be something that’s very easy to fix. For example, you may only be dealing with a blown fuse.

We put together this troubleshooting guide for Volkswagen A/C systems. The guide will help you troubleshoot the most common VW A/C system issues:

  • A/C not turning on
  • A/C not blowing cold air
  • A/C fan not working
  • A/C smells bad

We also have a troubleshooting guide for VW Jetta owners who are having issues with their heating system.

OEM Vs. Aftermarket A/C Parts

Do you need to replace one or some of the parts in your Volkswagen’s A/C system? You may be trying to decide between OEM and aftermarket parts. The vehicle’s HVAC system is pretty important, so it’d be wise not to cheap out on replacement parts.

OEM replacement parts are your best bet. OEM A/C parts are much more likely to last longer and perform better than aftermarket parts for these reasons:

  • OEM A/C parts are built with high quality materials and better construction practices. Aftermarket parts are usually built with low quality materials and questionable construction practices.
  • OEM A/C parts have the correct dimensions. They’re also compatible with the other A/C system parts. You can’t say the same about aftermarket parts. They’re not always built to OE specs.
  • All genuine OEM Volkswagen parts come with a good warranty policy that guarantees no manufacturing defects. It’s rare for aftermarket parts to come with any sort of warranty or guarantee.

This comparison guide goes into more detail about why OEM A/C parts are a better investment than aftermarket parts.
