I swapped the guts out from my old car to my roller doors yesterday. The roller had a manual crank window in it I guess they replaced it before it got painted and never changed back the motor. Anyway few beers later put the electrical stuff all back in. Since my car doesn't have a battery or pretty much anything in it yet. Can I jump the power window motor with a 12vt current and get it to move. It's a brand new regulator/motor too.
