Just about at the end of my rope... Windows haven't worked yet, and have not been able to find controller for driver's-side anywhere. Unfortunately, previous owner was very (VERY) mechanically declined and decided to hot-wire windows, so now the wiring is a mess.
Compound that with the fact I live on an island off the coast of Alaska, and pretty sure there are NO old GM vehicles with power window switches/harnesses intact (I've looked), not sure what to do. I did find manual door setups for all four, but as you can see in the pic the Burban's body isn't too hard on the eyes (pristine by Alaska standards).
So, anybody know a good option to repair this mayhem? Actually, a decent wiring diagram dummed-down would even help. Thanks in advance.

ITS EAsier for you to wire the switch and motor up to a relay. Thats what I am doing to mine because I have doors off a 1990 surburban with power windows.

This topic should have been posted in the electric section. But since I am here.
You said the vehicle was a suburban, but forgot to mention what year it was.
In the tech section, do a search in the search window at top right of page for wiring diagrams (http://forum.73-87chevytrucks.com/smforum/index.php?topic=11766.msg87585#msg87585) and it will pull up the complete 73-87 wiring diagrams (or just use the link I just added).
Let up know if you need anything else after visiting the wiring diagrams.

Here's a page that talks about rewiring with relays. Maybe it covers what you need. http://forum.73-87chevytrucks.com/smforum/index.php?topic=27076.0;topicseen

Sameold - FYI - The circuit you linked won't function as shown, because of an error in the ground path. Truck window motors don't ground through their frames. The motors function by reversing polarity on the tan and blue wire pair. The tan and blue wires are the only electrical connections to the motors. See the diagram posted by frotosride, shown in the thread linked by BADAZ.

Thank you all for the replies- I got the wiring squared away, and have diagnosed a short in the original 4-window switch. Any suggestions where to pick one of THOSE up? (I've checked Amazon, Ebay, and Dorman Products--still haven't found one). New or used, as long as it works and they ship to Alaska!
It's a 1986 K2500 High Sierra
Thanks again!
