    i still need some help here on my tailgate. this power window thing has got me up the wall so far im about to just put a damn manual in it! lol..i cant figure out were the single pronged orange wire with the little black stripe on it goes to..there are two plugs that come out of the tailgate...ones for the power window and all..the big round plug.but that other one..thats orange....has one prong with a little black rubber thing on it..its a plug..were does that go..any one know? or have an EASY TO UNDERSTAND wairing diagram? lol..cuase i have all my wires but that hoooked up when i try to test it..its laying in the back of the blazer...thought i would test it out in the new tailgate befor i put it on and all...nothing happens...so im guessing its this wire..considering it worked fine when i took it out of the old tailgate!

    I dont know about what color wire is what but........On my K5. There is a switch connected to the latching mechanism that wont let the window work if the tail gate is not closed and latched.
    I believe the switch is located inside the tailgate on the left side by the latch. Maby that wire goes to the switch

    no thats not it.. thats a small plug that goes over two prongs on the switch.yea i already checked that..this wire comes out right on the bottom..you can probobly see it when you open the tailgate..down on the bottom left..near the light wires on the drivers side....there are TWO cables coming out.im talking about the porange one that should be there...open the tailgate..and look there..should see what im talking about..i have no pics of it sorry...

    Okay last time I am replying to this stuff I have given the answer 8 -10 times now through e-mail PM's etc....here is the wiring diagram
    http://members.aol.com/fisherxt/rearwindow.gif

    If you can't read it show it to someone who can...regardless of wether or not the wire reaches to a constant power source it needs to be connected to a 12V source! look on the diagram orange always hot!

    precisely its the orange one that comes out of the frame that it needs to plug into might have to cut the end off the one coming out the tailgate and hook them straight together by means of crimps or soilder

    Yep that is the one you are looking for, I have had problems with my tailgate and that orange wire many times. The orange and black wire that runs thru the frame should be "HOT" at all times and should be connected to that plug coming outta your gate. If plug is no longer on the orange wire coming outta the frame you should just crimp or spice the 2 back together like "BowtieBlazer" said.

    Make sure you have a good ground on the motor, also it will not work with the tail gate laying down, it has to be in the up position to run. I had the same issues with mine.

    hey, any Chevy / GM truck dealer should be able to generate a schematic diagram of all parts and wiring,my biggest problem was contacts/lugs becomeing loose over time and not completing the circuit.there are some protection devicies in the wireing that are not absolutly necessary for the window to work,as long as the pos/neg.loop from the motor to the dash switch and the spring loaded contact switch inside the left upper tailgate latch are completing their circuits things should work.the key switch on the tailgate has always been the biggest pain in the ass to try to keep working!screw that thing/ the dash switch works!try 12 volt test leads then reverse polarity to your window motor they rarely go bad it`s usually connections not making contact that are the culprit! Good Luck,DWA

    If you have 12V to the orange/black wire then I would bet the switch inside the tailgate is bad, the one that doesn't allow the window to go up with the tailgate down. You can test for that problem by simply unplugging the switch and jumping the wires together. As previously mentioned, the window will not go up or down with the tailgate open.
