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.

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Remove the clips and screws securing the old window to the arm and slide it out through the top of the door (may need to be maneuvered out)

Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.

Testimonial: "You were absolutely correct. Low coolant level. Put in some 50/50 and we're nice and toasty now, but need to find out why coolant was so low. Thanks."
