Ford Repair: 1994 Mustang GT Air conditioning problem, emergency brake lever, bolt and nut

Question
Hi!
The other day when I turned on the the selection knob for my 94 Mustang GT air conditioning it started blowing air from the top of the dash (defrost) and the bottom of the dash (floor).  When I turned it on the heater selection it did the same thing. Before that it was just working fine. If it is a blend door motor problem, where is that part located?

Thanks,
Liz
