Switches Gradually Stopped Working on All Doors

2008 Chevrolet Silverado 2500HD LTZ, DURAMAX 6.6L V8 TURBO DIESEL, 4WD Crew Cab
First, both of the rear door window switches stopped working...
Then, after some time, all the driver door switches stopped working, except for the door lock switch.
But the driver door lock switch will not lock/unlock the driver door. However, it will lock/unlock the other three doors just fine.
If anyone has any idea on what needs replacing I would appreciate any help you can offer.
Thanks.

There are 2 different possible window systems and they are very different.
You need to check the RPO code sticker in the glove box and look for either of these codes "AN3 or DL3"

Here is the wiring diagram. This system works through the Body Control Module so you are going to need a high end professional scan tool to get into the system.

Ok thanks. I guess it's not a do-it-yourself fix then. Bummer
