2001 dodge dakota sport power window does not work from passenger door but will from drivers door

if it was the relay all the windows would not work, that being said now lets try to find it so I am going to assume that you've tried both window switches the drivers master and the passenger door and no luck if you take off the door panel on the passenger door and run a hot wire to the window motors connector and if the window functions we have a bad switch contact on the master and possibly the passenger door disconnect the plugs and clean them and if the switches can be taken apart clean the inside of corrosion and re grease with carbon conductive grease or w d 40 /p b blaster if you have no window function when you do the hot wire and ground connection then the motor is bad and must be replaced

The driver's door has a control panel with switches to control 2 or 4 windows, above those are two switches - the one closest to you is the power door lock and the one away is the window lock button. The image below has a red arrow pointing to the switch. Good luck!

look inside the rubber boot between the door and the door jamb wires break on both side inside the boot

Yes they make kits.

go onto a parts locator site on the internet and put in a request for the door-or call around locally to junkyards, you should be able to find one for less than $75.

check your window lock out swich on the drivers door if locked out or broken it will not lut passenger windowes ip or down

I susoect the passengers controller switch is faulty, bad connection in the wiring.

it's probably a broken wire in the door jam on either the drivers sid or the passengers side.check the wires where the fold wher the door opens and closes

1. check fuses
2. if motors are good, more likely it is, it will be the windows regulator or windows switch, both tend to wear out the contacts over times. the windows switch pretty expensive, its run about 123.00 buck each and the regulator run 59.00 each. more likely will be regulator. if it not the windows switch is good. hope that help some, both not hard to replace and not easy.

Find yourself wiring diagrams an test the electrical circuits . Do you know how to use a DVOM - digital volt ohm meter ? How to take the door panels off an check power an ground circuits to the switches ? If not , your best bet would be to take it to a qualified repair shop. You probably don't know what serial data network is ?
The B+ power for the door locks & power windows comes from a circuit breaker ,not a fuse . Circuit breakers very really fail .
You probably have broken wire inside the rubber flex boot from the body to the driver door .
