All the power windows quit working, which apparently is a common issue. The answer to this problem that seemed to fix the window issue was this. Open driver side door, turn the key on, hold the window button down and gently wiggle the rubber boot located between the a-pillar and door by door hinge. I did this and the window moved just a hair and that was it. Then it said to check the fuses located in fuse box on passenger side 10amp was 2nd one down on far left the 30-amp right below it I pulled both fuses both were good so I put them back in. Next was taking off the rubber boot to trace wires. I had to work so decided to wait on going any further. When I went to pull the car out of the garage I now have no power steering and no A/C and the airbag light is now on, on the dash. The air bag light is the only light on, and it stays solid, and message says service airbag. Please Help!

It sounds like you have found the problem in the wiring inside the door pillar. I would continue to take the car a part and inspect the wiring harness it must be damaged. I would also check all fuses with a test light.

If the wiring and fuses are okay, it sounds like the BCM has gone out or has corrosion on the connector so I would check that. To see if the BCM has gone out we should do a CAN scan, you can get a CAN scanner (Controller Area Network) from Amazon.

Here is a video to show you how:

Here is one for about $99.00 if you need it:

Here are the fuse locations and how to change out the BCM in case you need it, you can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Please let us know what happens.
