With the exception of an actually failing motor, all doors have regulators and tracks that the window has to travel through. So converting to manual crank windows won't necessarily be the solution if the felt is gone or the frames are bent, which causes the glass to jam in the track. Open the doors and fix the mechanicals. If the motor is done, then maybe it's easier to just find a used motor than it will be to swap all the parts. Or not, dunno. I can tell you that manual windows also fail and they are not necessarily all that cheap (for good used or new) or easy to replace the regulators in either.
