The tailgate handle broke on my '94 Toyota p/u. I want to know if I have to undo all 12 screws on the tailgate door (inside bed) to get a peek inside and if that is the way in to fix the problem. Right now the tailgate won't open: the latch moves up/down with no resistance. My guess is that there is a piece inside that broke. So really 2 questions: how to open a broken tailgate and how to fix the handle?
