There is a real bad squiking noise in the rear hatch and the button on the outside of the door to open the glass doesent work

more than likely the plastic connector for the latch inside broke, if you peel the carpet on the inside of the door down a little you will find a hole, use a screw driver in it to pop the window, then open it up and fix it. I repaired mine with a piece of light weight steel wire (type used for artificial flower arrangements, stole it from the kids craft drawer)
