How do you remove a back door panel on a 2004 Chrysler concord lx

There are panel holders made of plastic which hold the panel in and surround the door. Get at least two larger flat tipped screwdrivers, or a smaller pry bar and screwdriver, also a putty knife can aid in keeping scratches off the door
After removing the screws from the handle/armrest, remove the bolt from the latch, it has a little spring tension on it so you will need to hold it open with a screwdriver when installing.
Be careful to not scratch the door with the screwdriver by sliding
Once these are off, start on the rear bottom of the door and slowly work a flat tip screwdriver under the panel between the door and panel. (there is usually sticky tape and paper in between also).
Use a flashlight and while prying, locate the holder nearest the panel corner you are working. Once you locate the holder, pry the door panel away from the door right against the holder. Once you get it started it is easy to work the bottom and sides of the panel off the door.
Once the holders are out, the panel pulls up with plastic guides at the top against the window. When re installing the panel, ensure the guides are aligned before pressing them back into place.
