How VW A/C Compressors Fail ~ Video

Failing VW parts

vw POOR AIR CONDITIONINGToday we are back with more failed VW parts. We are right in the middle of a pretty hot summer. With a hot summer comes failing Air Conditioning. One of the most common things we are seeing fail is A/C compressors. We are doing several a week. The most common seem to be on 2.0t TDI (engine code CJAA) and 2.5 engines. It is not the only thing that I see cause poor air conditioning, but it is common.

    this is really sad!! the Failure Rate is high especially on TDI’s and VW will not acknowledge…..The A/C on my ex-2010 Jetta Sportwagen failed just out of Warranty…..I took it in and told them the problem and there response was we have to replace the compressor….Fortunately I had an extended warranty I had to pay 250 then the warranty company wouldn’t put a new compressor on the Car so I paid the different between a rebuilt and new Compressor so out of pocket was nearly $500 and the Warranty company paid $800 for a failure of a 75 part…..

    This guide will help you understand the components that get replaced when repairing a failed air conditioning system, as well as help to explain how all the individual components in the system work together to deliver cold air to you and your passengers.

    They may occur out of negligence or another failing component inside the air conditioning system. But even if you can’t escape from it doesn’t mean you can’t prepare for it. Take note of these signs that your Volkswagen Jetta’s AC compressor is going bad so you can fix them faster.

    Just watched VW compressor failed video – question I just had the heater core replaced would this cause my AC to stop working? Mechanic said what he did had nothing to do with the AC – just hard to believe since the AC worked perfectly before replacing heater core. Thanks in advance for any help.
