I had the same problem as listed above: The driver door window and locks stopped working out of nowhere. I printed the solutions and gave them to my husband. He found that one battery terminal was slightly loose - not much - and there was slight corrosion on the terminal post as well. He disconnected the battery terminals, cleaned the posts, left them disconnected for about 20 minutes, put them back on and TA DA...works like new. Boy, I sure am glad I didn't take this issue to a mechanic; no telling what the charge would have been.
Thank you for taking time to post your solutions to these problems; it sure does help!!
