Anybody wired up window module on Trooper

I am trying to install 2 Bulldog CL 200 window roll up modules on a 1996 isuzu trooper ls.  I pulled the door panel off the driver's side door and ran wires to the cl-200's.  I found the wire codes here.  The problem is that the only one that seems to work is the blue/white driver's side roll up.  The blue / YELLOW wire does not give any indication of voltage change.  At rest, using multimeter with negative lead hooked up to common ground, the blue / YELLOW wire which should control the passenger side roll up, shows a constant .625 volts.  When the switch is pressed down or up, the voltage remains the same.  I have spoken with a technician at Bulldog, but he was stumped as well.  What gives?  The only way I can see to solve this dillema is to run wires from all doors to the dirver side door (what a pain).  Can anyone with experience in isuzu wiring offer assistance? 

check the remaining wires inside the at the switch. Also this may sound stupid, but make sure that the drivers side switch can control the other window and make sure that you have do not the window override switch on so that the windows are locked out.Car stereo is a way of life. If you don't eat, sleep, breathe car audio, you don't even need to be around it.

I figured it out!  And yes, it was a royal pain!  Apparently Isuzu and certain Nissan and VW vehicles come with window control modules built into the driver's side doors.  These modules control all the windows via an IC that sends multiplexed signals to the other windows.  I had to run wires to the window motors on all the doors (PAIN), but now everything seems to be working.  I used the starter interupt wire to trigger the roll up, and the trunk release trigger (polarity reversed via relay) to the roll down modules.  Thanks for all who read my 1st post and tried to help.
