confirmed and certified

I had the truck 2 years I never used them ?
I had GPS ect installed 4 months after purchase.

Are there 3 seperate wires comming off the lock switch ?
Maybe I have a bad switch?


Thanks for input, i'll look under dash and maybe right side panel for that wire this weekend.

alright now that its confirmed and certified its still weird. go here http://hummeranswers.com/ and click on either front or back window wiring link towards bottom of page so you can see what im looking at.

it looks like when you press the lock switch that cuts the + that goes to center pole on the switches in each door. the motor is not directly operated by switch. switch goes to relay and then relay to motor.

So by the looks of it if it, the window will work when the dark blue wire has + going to the switch, but somehow its not stoping when the lock button is pressed.

Here is the weird part, all 3 windows are on the same lock switch, and 2 work but 1 doesnt. Something along the way is wrong but i cant put my finger on it. Nothing is cut or loose, since it has power, but something else is wrong.

I dont know exactly how the lock switch works, but if the 3 wires go in and make contact separately, maybe that one going to the window in question is sticking and not disconecting. have you ever spilled something sticky like juice or soda over the drivers switches in the past? that may be it if the switch works as i hope.

hope what i said makes the slightest sense.
