Window lock
My window lock stopped working. The light is on all the time. All the windows go up and down except one rear which goes down but does not go up. I have to use the key fob to close the rear window. It was working till a few days ago

I faced the exact same thing, fixed it just yesterday. You have to replace the whole window switch module.
Lift the silver trim around it with a pry tool, I found working it from the top and around worked best.
After you manage to lift that off then you have to lift the whole black plastic cover that's around the switch module, once again I've worked it from top and all the way around whilst pushing the leather over the plastic retainers.
Once that's out it's a simple matter of lifting the top trim from the switch module and replacing it with a new one.
I got my window switch from https://www.aliexpress.com/item/33041347830.html which saved a considerable amount of money.

Same Issues
Going through same exact issues after alternator issues. Belt pulley needed to be replaced from ripped belt and main battery was damaged because it drained fully to the point the car was dead. How did you manage to get window up with the key fob?
