I just purchased a used 2001 ford excursion and now my passenger power door lock doesn't work when I press lock unlock on the door or with the remote. And sometimes the back doors don't open or close either? :'( Does anyone know what is going on? Can anyone help?

I need to remove the door panel for the passenger side to replace the exterior mirror assembly. I've googled for directions or a diagram but am coming up short. Do you know if the how to for this is available somewhere online? Thanks!

My door locks keep locking and unlocking by themselves. How can I disconnect this system and control the door locks manually?

When I shut down the car, the gps plugged into the power outlet does not shut down, even with the truck totally off. I assume this will drain the battery. Is there anyway to make the power source shut off when I shut the truck down? I really don't want to have to unplug the gps every time I shut...
