Both seat warmers are on the same fuse, so my guess is that you have a burnt heating element.( independant from BCM )
For your rear windows if they failed at the same time, most likely the child proof switch is on or shorted out. ( not controlled by BCM )
Bulbs burn. ( not controlled by BCM )
You need a new turn signal arm. It happens ( not controlled by BCM )
If rear defogger doesn't work and fuse is good check for a burnt connector unde the rear speaker deck.( controlled by BCM )
Guy at Autozone knows diddly squat, Dealers are lazy and local mechanics don't get paid enough to bother with little things you can fix yourself.
If you fix little problems as they arise you won't find yourself with a whole lot of little problems all at once. None of these make it dangerous to drive your car car so relax and take one problem at a time, do a little investigating fix or get fixed one at a time and in a week or less your car will be like new again and you will love it again. Just take the time, if you have a question, come back here and one of us will help. Relax, deep breaths, deep breaths, one more and one more. Feel better?

Okay, my mistake 2005 has chimes in instrument panel so this means you either lost GMLan between "BCM" and Istrument Panel or the instrument panel speaker has failed.
