AIR WON'T COME OUT OF THE VENTS ON MY DASH BUT THE BLOWER WORKS AND THE RESISTER IS BRAND NEW

I change the final stage unit(resistor), I can hear the blower working, air comes through the floor vents strong, but weak through the defrost and not at all through the dash vents. What could it be?

Do you
have the same problem?

Well I'm a novice mechanic, but I'm pretty good at thinking my way through tasks so any direction would be greatly appreciated. Maybe what to check next or the next 2 or three things. Thankyou for the replies this is great!

The next step will involve the scanning of the IHKA system to see if there are currently present faults. Seek out someone locally with proprietary BMW scanning tools.
