Hi Everyone

The cold has started outside and a problem we’ve had with our air con is now causing issues. We took the car to our local trusted garage (none VAG) a few weeks ago and they were unable to identify the cause despite no lack of trying.

I’m hoping this issue has come up before and there may be a root cause and solution. Here’s the symptoms:

Aircon temperature set to LO (lowest temperature) the blowers seem to work (can adjust the airflow from from low to MAX as usual) but the moment you turn the temperature off LO, to 16, the blowers stop pushing air out. This means if you want any hot air in the car nothing is pushed out.

Changing the direction setting to feet/face also seems to stop them working (but I’m hearing that one second hand)

Any help or link to related articles greatly appreciated

Thanks

Diesel or Petrol?

Might be timely to raise the post about my woes back in 2018 with my 2015 vRS TSI, which started with no cabin heating:

Ours is Petrol - 2015 VRS TSI - will read your post there now

Have you done an HVAC flap reset?

Tried that - thanks for the link - it did the re-calibration, but hasn’t fixed the issue

Might be time to have a diagnostic scan to see if there are any tell tale fault codes.

Another thought - do you have a silica bag ‘Mit Silikat’ in your header tank, and if so, is it intact. When they fail, they can gum up the heater matrix.

Thought I'd close the loop on this. After a 3 month wait to have the car looked at at the dealer (... 3 months!), finally took the car over for its booking.

Their notes: Confirmed blowers are INOP when on anything higher than LO, carried out skoda diagnostics and no faults stored and no factory guidance. carried out function test and found blowers started working. removed pollen filter to check recirculation/fresh air flaps and found fresh air flaps working as required but recirculation flap was stuck closed. dash and cross member removal required to replace recirculation linkage and rectify fault. replaced re-circulation flap motor and tested - all functioning as intended.

Needless to say the cost of the re-circulation flap was nominal. The cost of taking the dash apart was not!

But, we are now back up and running, just for the cold weather to start to pass!
