no wires it has metal prongs on it. it was plugged into a fuse box under the dash on driver side left corner. Ill take a pick and post it up in a few

ok, i ordered a new window switch and im hoping that will clear up the issue but here is the black box relay i was speaking of.

that is the audible key in/door open/lights on alarm.

and that should have nothing to do with the windows either.

Ok, on to the next. I will follow up after switch install

Update: so I installed a new window switch. The locks are working excellent, the passenger window rolls down. The driver side isn't budging at all. I don't hear any relay clicks when I press the button and there isn't any sign of movement so am I to assum it's a stuck motor?

window system on gmt400 platform does not use windows. verify power at motor plug when pressing switch.

ok i will run that test this weekend. Do these trucks have motors that can be installed separately or would i have to get a whole regulator setup just to replace a motor?

either way.
