The one peice that fell into the door is the sissor part. That attaches to the reg and when the motor moves the gear that pushes the window up. Those white/yellow tabs should sit on/in that channel that fell out and then the glass in it. If you want pull the other door panel off and see how that side is and try to put yours back together. Now as your motor doesnt turn? Ck for power at the motor plug. Probe the back with a test light, when you hit up, 1 should power up, and down the other should power up.
