Hello people I need some help, I did some modification on my a3 2005. From a3 2012 I got complete 2 din console with rns-e and climatronic. When I installed all parts I realised that climatronic is working properly but when AC button is on, there is a problem. You can hear that air condition is working but there is no air blowing into cabin. Why is that happening and can that be solved?
