It happened shortly after I bought it. even then it happened gradually, sometimes it worked fine other times the air flow stopped. It was different each time I started the vehicle for about 3-4 weeks then it stopped working I'll try the battery disconnection the first chance I get and let you know. Thanks for your time to read and consider what it might be.

... I mean, I don't think the pipe work that feeds the pollen filter is blocked. Also the pollen filter does not look particularly dirty or full. So have popped it back in. Picture attached above. Thanks for reading and considering this post. Happy for any other suggestions as I don't know exactly how the system works and what to check next.

Thank you I've just removed the pollen filter and tried the system as before. That's correct. With the pollen filter OUT the Recirculation function does NOT filter the air. However, unfortunately that hasn't changed the air flow in any way. The fans still do not blow when the Recirculation functio is OFF. This is true for AC ON and AC OFF. There is plenty of noise from the system sounding like it works. Also, when the Recirculation function is OFF there is plenty of airflow coming through the open pollen filter area, so identity think there's a problem of this pipework being blocked. Does that sound like a reasonable assumption?

Thanks If the air con if OFF there is still some air blowing from the fans. It varies I've added a video to describe and show each function with the air con ON and OFF

The air con system only works in recirculate mode. If the recirculating air function/button is switched OFF then there is no air blowing from the fans on the dashboard (windshield, front or foot well fans. This has happened gradually over a few weeks. At one point there was intermittent air coming from the fans on the dashboard without the recirculate function. For instance it would still create warm air with AC function on however the fan would blow intermittently. Now the system only blows air while the recirculate function is ON. So while the air condition system does appear to work and sounds like it is working however no air blows from any of the fans unless the recirculate function/button is ON and this is really not as effective at de-misting the windshield on cold mornings! Any ideas of what could be wrong? How to check or confirm the problem? Including how to avoid a to avoid or reduce the big (expensive!) job of removing much of the dashboard to get to the systems to assess what the problem is? Model: Fabia Elegance 1.6 TDI CR 103BHP
