I had the same problem in my wife's 2003 Yukon Denali. The power seats and passengers side window wouldn't work. Turned out to be a blown Buss Type fuse in the Underhood Fuse Block. It is the one marked MBEC 1 50amp. Hard to tell if the are blown so look very carefully. Should look like a hoop with two shiny solderlooking bubbles on either side. On my blown fuse, it caught my attention because it looked like the solder was missing and I had to look very closely to see the bottom of the "hoop" was open. They are very hard to remove and must be pulled straight up.
This type of fuse looks like a red square with a clear plastic top showing the fuse link under the plastic. On my vehicle it is on the top row second one from the left.

You will need to remove the door panel to gain access to the handle. Roll the window up or down as needed to get to the nuts that attach the handle to the door. You will also need to remove a rod the goes to the door lock. You will see the rod after the door panel is removed. Good luck.

If you've replaced the actuators and they are working.
One of the blend doors may be broken inside the heater box. To repair or replace the broken door you
have to remove the heater box. This is not a small job. The book gives 6-7 hours for the job. There is a
cheat that I've heard good things about. I guess it can
be done in a fraction of the time. You can find out
about it at heatertreater.net I have not used it myself
but I know somone who has. And it worked well for
him. Hope this helps.
