With the A/C off can you get the fan to blow down at your feet without the defrost blowing, can you switch to defrost and no air at your feet? Can you switch to vent and shut off the other 2? I'm guessing you can't shut off the defrost. I too don't know where the hell those doors are, someone else will have to chime in.
Sounds like 2 different problems. Check that vacuum is available at the control panel and from there to the blend door actuators. As for the blower motor not blowing hard, check the wiring to the speed resistor mounted on top of the air box behind the glove box.
