I had the same Problem on my 87 suburban
I only paid 700 also,
I have spent a total of about 8 hours on the window wiring
and learned alot along the way
You keep saying you had the switch defeted? But have you
checked the wires for continuity?
The tan and the blue wires are the power up and power down
the orange/black is always hot for the power key switch, they run right next to the hinge and might have been cut or broken internaly !!!
Also check the ground ?
If you look insde the tailgate next to the passenger side latch you will see the
latch switch the latch must be fully locked to engage it
Stick your little finger or a screw driver to close the latch. If it works
Just dont let the window fully extend with the tailgate open!!
the glass cant handle its own weight and will brake!! Believe me I know !!! (DOH)
