Just purchased a 2017 Pacifica. No problems until I tried to open the drivers side sliding door today. It just beeps. All other doors work. I get a screen message that says power not available, must be opened manually. So I did a bit of research and see the post about sliding the switch on the wiring harness. I followed the instructions. Not only didn't work, but now passenger side sliding door won't open either! Same message on screen. Any ideas! Does a FOB battery going dead act like this?
