no power to windows and locks, rear only
I have a 2005 Silverado 1500 4 door. Yesterday morning I had a strong smell in the interior (at first I was thinking chemical/solvent, but maybe its smoked electronics?). Some problems kicked in at the same time. Now rear door windows and locks don't operate from either the drivers or rear controls. Locks don't auto activate in drive or with remote. Front windows, mirrors, heated seats and locks work fine.
The airbag light and service airbag message also started at the same time. Not sure how this would be related, I've had a sensor go bad in the past, maybe the other side is spent now?
Tonight, the info display is showing the passenger rear door ajar, but the door is closed, message doesn't change when open or closed.
Rear door speakers are working fine. no change in the window and lock issue though.
How are the rear door windows and locks controlled? Do they use the DDM or BCM or another module?
Does anyone have any idea what could be happening? The window and lock circuits seem to be set up left and right since the fuses and breakers are set up that way, so I'm not sure why only the back doors are having the problem.
Is it worth resetting one of the modules? If so, how do I do that?
Thanks in advance for any ideas.

Two things I would look at or do.
First, I would check the battery cables (especially the ground) and make sure they are nice and tight.
Second, remove the negative ground cable for a few minutes to reset the computers. Not technical but it gets the message across..."sometimes these computers get brain farts." Resetting them with a battery disconnect is sometimes all it takes.
Here are some schematics. Hope they help; I having got time to really look but if you want some further input must let me know; I'll probably be back on tomorrow or the next day.
