Luckily, this is the easiest flap to get to!

down under your dash in the middle you'll see a black box. On the driver side of that box you'll see a little gear motor. If the selector to the face vents is still working, I would assume tthat gear motor is good. The motor will have two levers attaching to it that operate a couple of flaps. One flap controls the defroster and the other does the floor to face vents. You might get lucky and find that the lever has just come disconnected, but I had to wriggle my hand way up inside the dash after disassembling it to place the flap back in it's slots.

I'm not sure what you drive, but I'm assuming that it's a similar GM configuration because it seems to be a common problem
