1988 town car rear windows go down wont go up

Rear window sounds like a window regulator.

take the window regulator out and see if you can manually move it to the down position, if you cannot them try and connect that regulator to another window motor, and get it to the down position that way. then reinstall the regulator and window, good luck

First, Dodge Caravan,Plymouth Voyager, and Chrysler Town And Country are all the same basic minivan. Next, passenger and driver side windows are the same. They simply 'flip over' from one side to the other.
You need to be sure if you have a Grand "xyz" or not. Grand models are longer, and use a longer rear window. Middle windows are the same length either way.
I know that 1984 through 1992 windows are interchangable as long as you match Grand to Grand, and non-grand to non-grand. I think you can use up through 1995, in 1996 they redesigned and the shape is a little different.
Oh, and try to get the factory tinted rear windows if you can, they will help keeping cool in the summer (the middle ones help a LOT if they are tinted)

This is a cable driven system and the cable may have a worn opening that is causing it to slip. The other posibility is that the drive motor gear itself has stripped. Thank you, Dana

Sounds like the plastic gears on the window motor have wore out and may be stripped or the window is partially off track.

YOU PROBABALY MAVE A BROKEN WIRE IN THE HARNESS THAT GOES FROM THE DRIVERS DOOR TO THE INSIDE OF THE VEHICLE

remove te rear trim panels and replace the window regulators, this is very common.

So as not to be repetitive, for the failure of your power driver side window and rear window, review this handy diagnostic article, which identifies the possible causes, from a bad fuse, relay to window motor, etc.:

This should help narrow down your particular cause.

2 screws on door pull and door clips around outside edge of door panel pop out with flat screwdriver then remove panel some motors you can replace just the plastic gears oriellys parts stores carry them obout 15 bucks good luck

If the window regulator motors are running & the glass is not moving, then either the drive assembly is broken & you need new regulators - which is the most probable cause, or the bottom window channel that it hooks to, got unhooked or separated from the glass. Hope this helps you, Rick
