reverse order to replace door handle

I think some of the Durangos have this as a regular fault. The only way to open the door is to gain access to the latch inside the door panel. You will need a cross head screw driver and a flat head screw driver. As well as a flashlight and some WD40.
Drop the rear seats and empty the trunk as you are going to have to sit in it to do this. Carefully remove the upper window trim. It is clipped in so it should pull free with a bit of patience and effort. This should reveal two cross head screws, one each side. Remove these. The lower trim panel should ease out far enough for you to see, using the flashlight, the release latch at the bottom of the door. The latch is connected to the handle by a rod so follow it down to find the latch. The trigger arm moves up and down.
Using the flat screw driver and using the handle connecting rod as a guide, push the latch trigger down. Applying light pressure to the tailgate might help it let go.
You may need to disconnect the rod at the top to get enough slack to move the latch release. I think it just hooks out with a small screw driver.
Once the tailgate is open you can then fully remove the lower trim to get better access for repairs.
