The generator or the alternator
Underneath the backseat
You'll still have the wiring running to the doors, but yes. There's no problem in replacing a power window door with a manual. The other way around is much more difficult.
If the windows don't go all the way down, it is likely they are designed that way because of the shape of the door and can not be fixed.
LoL, well it depends if its power windows or not. If it is power there are two switch's that are for driver side and passenger windows located on the the door trim of the driver side and if not power just use the cranks on the doors.
The bcm that controls power windows, locks and doors is located on the driverside floor.
Where do you add power steering fluid on a 2003 Pontiac Bonneville?
For a 1987 there is no automatic doors or windows for A Chevy Astro Fuse is underneath the steering colum along the Driver side feet...
You'll need to add the necessary relay and fuse, you'll probably have to do the wiring yourself, and you'll be better off to take the doors from one which already has power windows, rather than trying to convert yours to power windows.
Have you checked the relays?
Either there's a crank on the door which you turn to roll down the window, or there are buttons in the center console which actuate the power windows... if the doors have been taken off of the vehicle and the power windows aren't working afterwards, make sure they were plugged back in when the doors were reinstalled.
Not possible without ripping doors and wiring apart - don't waste your time and money
I would not see any way of this working. Completely two different set-ups. You have the old Sportvan and are wanting to use parts from an Express van. To say nothing of the wiring, switches & relays to convert to power windows and locks with the right parts.
