2006 GMC sierra driver's side door power locks and windows not working, indoor lights stay on

SOURCE: HAVE A 03 GMC SIERRA

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 should check the wire harness that goes from the door to the truck there must be a bad conection near by there somewhere in the harness hope this could help you.

The control may have gone bad... You'll need to 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. Then you can disconnect the controls and test them

if your main switch panel still works the passenger window and if door locks still work probaly bad window motor
