All of a sudden my AC blower started making a hell of a vibration/racket on high speed. A few days ago, I distinctly smelled "mouse smell" inside the cab. Since the blower motor is only a year old, I figured a mouse had gotten in there, which it had along with one baby (yes, I searched for more). After pulling out the newly dead mice, I sprayed everything with chlorox and reinstalled the blower motor. Now, no matter where I set the blower vent control, I only have air blowing out the defrosters. I may have inadvertently pushed on the interior vent door located just inside and above the blower motor while cleaning. Any suggestions for restoring all controls? They all worked fine before taking the blower motor out. This is on a 2001 2500 where the motor is located beneath the glove box.

Make sure you reconnected the small vacuum line next to your heater core, it controls all of the vacuum actuators.

Edit:
Oops, I see now it's a 2001, looks like you are in the wrong section but the same idea applies,
Check your vacuum lines.
