Re: electric motors in the doors
Take off the doorskin
You will see there are two bolts holding the glass into the winder mechanism - undo them. The window will need to be fully up, fully down, or halfway up.
The winder mechanism is secured by three bolts through the door.
The motor itself is secured by a set of rivets, unless it's been changed before. I usually knock the rivets back through the silver collar with a screwdriver/hammer, and then drill out the collar. Use some bolts from the hardware shop to reattach.
It'll also be worth using a lubricant on the window tracks while you're there, such as graphite or a silicone-based lube. Most likely the sluggishness is due to the motors being old and weak. They wll be very dear to replace, but if you're lucky you will find a wrecker who'll let the motors go for about $75 or $100 each.
