manual to power window swap...PLEASE HELP!!
 

so we were swapping doors, but the new door had a manual window, so we wanted to switch out the power window from the old door to the new one....got everything hooked up, and we were testing out the window....as soon as i connected the power to the window, the window automatically went all the way down by itself and wouldnt go back up...further inspection shows that the beads that ran the windows came out too far or something, and right now we're currently trying to feed the beads up to the track but its like the motor isnt getting power...i dont think its a power problem because the passenger window still works fine..anyway im sure i might have confused some of you so heres a picture

desperately need help as my friends fc is now sitting in front of my house without a door on...thanks guys
