Removing inner door panels on truck

Typically these are held in place by plastic push-fasteners and will need to be gently pried off. Suggest contacting the dealership where you bought and talking to a tech, who will likely have a trick to do it without damaging the door panel.

I will be as detailed as possible to help those like me who've tried to figure out from a dozen partial answers. 1. remove the triangle trim piece at top of door panel that is opposite the side view mirror - do this by hand, pulling it straight out, so not to break the internal clips holding it in place. Next remove two small pop outs - one near door handle and the other near top of door. 3. under the door handle there is a silver circle that looks like a screw with no slot. use a tiny screw driver to pull this out about 1/4 inch, releasing the plastic door handle. 4. using the tiny screw driver, pull out the small square pop out on the door lock. It only moves slightly, then the lock pulls straight up. On the bottom of the large thing you pull the door closed with, using the tiny screw driver, pop where it's obvious, and the silver strip will pop off. Remove the 10 mm screws. Then find a loose area and pull straight out until you hear a pop. continue around the bottom snapping out each clip and the door will lift off at the window. Don't move it far, because you need to unplug 3 items near the window controls. I never figured out how to unplug the door handle unit, so i simply held the door panel while I finished the install. Suggest you have a long handle magnet available to fish out any loose screws you might drop. Hope this helps someone.

glad to know I helped. Seems like this kind of information should be in owner's manuals and not so tough to find, but until then sites like this help me alot. Glad to give back when I can.
