New blower motor - very little air out of vents

My 2008 X3 blower motor started the 'death chirp' this winter so yesterday the dealer put a new motor in. I picked up the car and the blower motor runs strong but little air comes out of the vents unless I set it to defrost then I can actually feel air pushing out of the defrost vents(not nearly a strong blowing though). With it manually set at 'footwell' and fan on high I can feel it blowing a bit. With it set manually at 'dash vents' and on high I can barely feel the air coming out. Set on auto, the car eventually warms up but little air felt trickling out of all vents. All of the actuators are working , the recirc door works and the fan motor reacts perfectly to any change in the controls. Any ideas of what to look for? Iv'e searched a lot of forums but little to no X3 specific info is available.

Thanks,

Aaron

If the dealer installed it, I'd be right back at the dealership asking them what's wrong. Maybe they disturbed a control cable.

Well I think I figured it out. I took off the blower housing lid and removed the micro filter and there was an old parking garage stub and a piece of concrete??? stuck in one of the inlet holes. I cleaned out the blower box under the filter, put it back together and the air flow is much stronger. The dealer must have removed the assembly to get to the motor without looking under the filter to see the obstruction.
