Can't get the pwr window to go all the way up even after replacing motor

You can't. The motors draw a lot of power, it has to go through a relay. Don't try and work round it, fix the issue. Go down to a local breaker if you need a switch unit.

There is no way to ever know what a vehicle
repair would cost & only a fool would quote
a price without first diagnosing the issues AFTER
they have things apart
The last shop let you down
Most window problems are a broken window regulator
Could be the switch was worn & was replaced,the relay
if there even is one & windows seldom have a relay,they just
have a circuit breaker for the motor.
The regulator was going & they failed to remove the door panel
to check it

The window motors don't have brushes to replace,
you should see & feel that,as your inside the door

You remove the regulator assy & motor together,
then the motor

You will have bolts to remove & possibly rivets to
drill out

Finding a wiring diagram an testing power an ground circuits is the way to a fix .
How To Diagnose your Power Window Problem Is the Switch or motor bad
The Trainer 24 Power Window Troubleshooting

Remove the inner door panel & replace the broken
window regulator cable

I had an 86 Deville

You have to drill out the rivets
-- to remove the window regulator & motor assy

If the motor is bad (test it-put battery
12v to it) then you drill out the smaller
rivets to remove the motor & keep the
window regulator if good.

If the regulator is bad, remove the good motor
& put it in the new regulator

The regulator can be bolted back in as you
will not have a big size pop rivet tool for that,

Before you remove the rivets, check the height of the
window glass above the door,when window is down
You can set it just above the molding per build or down
even by adjusting how you bolt the regulator in

The regulators wear out & cause a sloppy window movement
& the plastic on top can not be fixed

nor can you afford one.

Junk the stupid van and get something else

sounds like the motor burnt up replace them

I beleive you need to change the Power Window Switches Module in the drivers side door panel, as these connections are interlinked within this module and it is usually the first part that fails. Especially that you already changed the switches & motor in the passenger door and it still does not work. Once you remove the dual switch module in the driver's side door, you will understand what I mean. Plus it is really easy to access. Good luck! I have the same model, Claude
