Weak air flow cabin
 
My A/C hasn't been very good for a while. Then I had a accident which caused replacement of the AC condenser. The rear evaporator was leaking for a while so had that replaced too.
When all was done I now notice the air flow is not strong at all. It cools but even with max air flow (12) it is not what it was before.

I replaced the blower motor a few years ago and also with AC off the air flow is weak.
When I switch the AC on there is a change of air flowing noise close to the blower motor, like it creates a hurricane but unfortunately without the wanted air flow.

Any ideas where I should start looking?

When was the last time you changed your cabin filter?

Pull codes, may have a flap motor stuck. It will show up in VAG-COM...
