2004 GMC sierra 2500 crew cab. I have lost all power in driver door meaning no power locks, windows, power mirrors, or heated seats. All other windows and power locks work fine. Pulled panel off nothing disconnected and nothing looks cut my guess is the window switch is gone, and other suggest before I buy new switch and hope thats it

Wire broke in harness between door and cab .

will check that

That's a lot of broken wires! Those circuits are on different power feeds. Power door locks and mirrors are generally hot all of the time. Windows and power seats are only hot with key on.

Only one ground for all.

I had a problem with my power window switch in my 2011 silverado. It wouldn't roll up the passenger window. Switch had a short inside it. Only way to fix it was to buy a new switch ---- 900 bucks is what they were new. Found one in a junk yard

if it is a switch issue rock auto has a good variety.we just replaced them on a buddies truck
and at a good price

Could be but without a diagram we're all just guessing. Passenger window usually goes back and grounds at the drivers side especially if it has auto down.

I think around that year the switch is called a driver door module , If so the new one will need to be programed before it will work . Pull the switch out and test for power and ground on the larger wires on the switch . Ground is black B+ could be red , pink or orange . I can't look at the GM diagrams any more after I quit working at the dealer.

Thanks for all the suggest. Problem solved it was the window module switch panel replaced no programing needed

thanks
