I bought this explorer over the summer and it had a problem where the bumper had been pushed in and the plastic on top of the bumper caused the rear door to not shut all the way and the door ajar light would be on unless you slammed it. So today I tried to do something good and I fixed the bumper so the door would close correctly, then I tried the door and the second time I went to open it the handle up above the license plate felt like it broke or something and now it doesn't unlatch the door at all. Door is stuck shut and latch handle just moves freely. I'm thinking I'm going to have to rip off the plastic door panel to get inside the door? Any tips? I also noticed the hinges on the glass portion of the door are loose.
