Use your voltmeter.  There should be +12V on the top terminal of the
door frame with the front locks up, and on the second terminal with
them down (or the reverse, I may have mixed it up).  Third terminal
is not used and fourth is ground.

With the slider ajar, clip a jumper lead to the bottom terminal, and
a second jumper to the second from the top.  With slider lock up and
front door lock down, touch the leads to their corresponding terminal
on the slider -- slider lock should go down.  Clip the jumper to the
top contact and pull the front door lock up.  Now when you touch the
leads to the contacts the slider should unlock.  Again, I may have
this backwards.

If it works like that, you're not getting good contact on those
pins.  On mine the slider contacts were a little too low and the pins
in the frame were landing on the plastic above the contact instead of
the working part.  Clearly the slider was a bit low.  As a temporary
measure I moved the slider contact block up slightly by enlarging the
mounting holes, and filed a slight 45-degree chamfer in the top edge
of the pins in the frame.

Yrs,
