Is there any way to see if there is foreign object jamming the mode door in position?

I have 07 Screw when I pulled the side panel off my dash to run my Evo cable I heard something come loose and sound like it fell somewhere behind/in the dash.

I didn't think anything of it until I went to use my defroster this morning and it's stuck in vent. I can hear the pass. side doors move and the blend works fine.
