This is a bit of a long shot-because I can't remember where the door buttons are located, or if they are part of the hinge on this vehicle. but if you have door buttons on the door frame and I don't mean door handles, but buttons that usually have a rubber cover and are in the door frame not the door, pull that cover back enought to squirt some WD40 into the body of the switch, then push it several times on the theory that it will loosen up any corrosion in the switch. Start with the drivers door, if that does not solve it go to the next door until you cover them all. I seem to recall a particular problem with the closed door sensor on the sliders, so I'd check them carefully. Hope this helps.
