Hi all. I've got a 1999 classic diesel auto with a locking problem, the tailgate lock is jammed preventing the tailgate from latching and closing. I've tried remote locking and unlocking but the lock refuses to budge, even with the tailgate wide open the hazzard warning lights flash and the alarm will set. I've occassionally had the open tailgate light on the dash alight when the taigate is firmly closed and have had to open and close again. anything to do with it? Dog had to sit in the passanger seat on the way home in case the hatch flew open, he loved the leather. Help please. Toby
