Original owner, 1990 240sx. The hatch door has stopped engaging the latch. I took the covers off and fiddled with the vertical settings. When I operate the latch from inside the rear compartment, it generally functions, but when I try to engage it by closing the hatch door, it doesn’t work. I’ve lubricated it and worked it repeatedly to be sure it is loosened up. The key mechanism works when I am operating the latch manually. What’s the secret to the adjustment I am missing, or do I just need a new assembly? I have not yet completely removed the latch mechanism from the body, hoping there is an easier solution. Any suggestions appreciated. Note that the latch has worked without adjustment for thirty years.
