Default Back window is possessed- randomly goes down by itself

I need help! Yesterday I went out and noticed my back window was down. I didnt think anything of it, figured my wife forgot to raise it after pulling groceries or something, so I put it up.

I drove to the store today, and when I pulled in the parking lot I noticed in the rear view mirror the back window going down by itself. I put it up, and as soon as I let go of the switch it went right back down. I parked, put the window up, and immediately pulled the key out. The window stayed up. As soon as I came out of the store, I noticed the back window down again, and all the doors unlocked. On the way home, the window went down again, and this time I noticed the door locks clicking while the window was moving. Any time I tried to put the window up with the switch, it either did nothing, or it would go up while the locks unlocked-locked-unlocked-locked until I let go of the switch. As soon as I let go, the window would go down and stay there and the locks would stop moving.

When I got home, I parked, put the window up, and immediately pulled the key out again. The window stayed up. About 20 minutes later, I went out, the window was down, and the doors unlocked. This is going to be a real problem!

I dont have the fob, just the key. The only keyfob we have is on my wifes keychain and it was nowhere near the truck during any of this.

Any ideas? Fried rear window ecu? Bad switch? Short circuit somewhere? I can pull the rear window motor wire connector as a short term fix to keep it from going down, we dont really use the back window much anyway. But having the door locks involved randomly opening the locks, thats a problem. Anyone have any ideas?? Wife just got laid off from her job, not a good time for this.....
