Every winter when the weather turns cold, the sliding door on our 87
Westy develops a tendency to unlatch spontaneously.  Usually it just
takes a couple of extra tries to close it and to leave it locked to keep
it from popping open again.  But this year, it just won't close anymore!

So, do I need a new lock assembly or is there something to adjust that
will resolve this problem?

Thanks,

Bryan
