The tailgate lock on my 1993 S-15 Jimmy is broken. A key fits in
the lock. It normally is twisted CCW to release the glass, and is
twisted CW to release the tailgate. The entire lock core is gone, as
if it was drilled out. The remaining portion of the cylinder is still
in the gate.
I have a replacement core and cylinder from the dealer. I can't
see any of the mechanism inside of the gate to open either the glass or
the gate. I need to get the gate open to be able to replace the lock
assembly. I've been inside the vehicle and there doesn't seem to be a
way to disassemble or trip the latches.
Are there any words of experience available? By the way, I went
to the local Chevy dealer and bought the parts. The parts guy referred
me to the technical specialists for advice. I described the problem to
the guy (actually young kid). He had the classic deer in the
headlights look and actually said to me....."I'm not very mechanically
inclined". Needless to say, he wasn't able to help me, and was
obviously not well suited to his position.
Any insight would be welcome. By the way, I also replaced the
drive motor on the drivers' window, and have posted some tips on that
