When it rains, within 24 hours, the windows do not automatically move down enough to open the door on command of pulling the door handle. This disallows the ability to close the door back if the door is open, barely underneath the lip of the sky panels. Because of this power loss, the mirrors do not open, the door locks do not work, and the windows do not work. To be able to re-close the doors, the sky panels must be removed and either left off or replaced. Essentially rain leaks into the body where wiring that controls door locks, door windows, causing electrical failure of this circuit only.
