91 Mazda MPV doorlocks - problem?

did an Autostart AS1725SH on the above van today.  went smooth as silk (best in a long time) other than the doorlocks.  I found the GREEN/ black wire under the pass. dash, and it tested as it should have.  However, it doesn't work!!  I can pulse ground on the lead and the doors will lock (as they should).  opening the circuit should unlock, and it doesn't. 

testing revealed that this is a toggle system.  manually unlock the doors, the wire tests at nothing, BUT with a slight voltage bleed of about 4 or 5 volts.  Manually locking the doors puts the wire at ground and it stays there.  I'm stumped...wired the relay exactly like the diagram showed, and it would lock but not unlock.  I get the feeling that something is wrong with the vehicle...

the when the circuit is open, the side going to the module is the one that bleeds voltage.  the other rests at absolute zero.  when the doors are locked, it goes to chassis ground, and stays there....

any thoughts?    b

if you re-read my post, I "wire the relay exactly as shown in the diagram", and it only locked.  I'm convinced that the bleeding voltage has something to do with it.  In the configuration you list above, locking will pulse ground on the circuit, and unlocking will open the circuit.  this is EXACTLY what I did.  I wasted a lot of time trying to work it out manually....

I found the GREEN/ black wire at the timer mod. under the pass dash as per instructions.  I opened the wire and connected a pair of my own wires to run across.  from there, I could NOT get it to function as the diagrams show even manually controlling the wires....

I'm stumped!!

is this what your diagram shows

output to the relay should be negative

if it does not work then the wire that you cut must be hooked up backwards

also my colors show using a GREEN / WHITE

whoops sorry about that

that is the diagram that I used.  followed it to a tee!!  I got the sheets from several sources, and they all said GREEN/ black at the timer mod.  the wire I grabbed does indeed do the doorlocks, as I can lock them.  just not unlock.  If I open the wire, the locks don't work, I close the circuit, they operate normally...this is definitely the right wire.  what source do you have that says GREEN / WHITE?  designtech?

now that I did some digging, I see that techsoft shows GREEN/ black.  designtech and bulldog both show GREEN / WHITE.  reason why I took techsoft as better as it was BANG ON on the rest of them, where the other two were wrong in a few cases (parklamp, etc were wrong).  there were a few wires going to the timer mod, and as soon as I saw the GREEN/ black and tested it, I stopped looking.  is it possible that the wire I grabbed is wrong?  anybody out there find this one out the hard way too?
