anyone ever ran into this problem? i got a 91 explorer xlt 4wd the back hatch glass doesnt lock at all. i lock the rear hatch door with key or from inside makes no difference i can still turn the handle in the direction to open glass part and open she comes. not a very secure feeling knowing anyone could pop that open and get right on in. anyone that may have had similer problems or anyone that knows how to fix this id really appreciate the help!
