how to replace passenger side power window motor on 2001 Dodge van

The procedure is as below,

first the door panel needs to be removed:---

It is essential to remove the door access panel of the vehicle to begin to replace the power window motor. A door panel is primarily made of plastic. You must remove all plastic parts, the casing around the door handle, and the screw hole covers.

NEXT the switch panel has to be removed:---

This panel is located below the switch for the operation of the power window. To remove the panel, a small pry bar is used to gently pry the panel up. Gentle force is best since breaking of the panel will result in having to buy the panel, which can be very costly. There is a special small pry bar tool that can be bought to remove the panel more efficiently.
After the panel is removed, the safety connector needs to be released.
The main door panel needs to be removed next. There are mounting bolts and/or screws that connect the door panel to the door. These need to be removed. Great care needs to be exercised to be sure not to break the plastic push style fasteners. After removing all the bolts, screws, and fasteners, gently pull up and out on the door panel.
After removing the door panel, there may be a weather and sound insulator attached to the door. This insulator looks like a thick piece of plastic. The insulator needs to be pulled back or removed to expose the inner workings of the door.

The next step is to secure the window. The best way to secure the window is to use masking tape. Not securing the window for the removal of the window motor and regulator could result in the window slipping, sliding down, and causing serious injury or damage
The next step in the process is to remove the window mounting and regulator mounting bolts. There should be one window mounting bolt, located about 5 inches downward from the back side of the window. There are two window regulator bolts located about 5 inches apart and diagonal from the window mounting bolt.

Since the bolts have now been removed, the regulator should be easily removed. The window regulator consists of the window regulator rail and the regulator cable. The power window motor is attached to the regulator rail.
