About a month ago, went out to my van and tried to open the power sliding door on the left side by the remote and it would not open or unlock, so I tried to open it manually no luck as well. So from the inside I tried to manually unlock the door so I could at least open the door manually but not a chance. so I also tried the open buttons for the sliding doors on the door post B-pillar and also the control buttons up by the rear view mirror. There is literally no way to open this door from the inside or out, all the other doors are working fine with remote fob or control buttons from the inside.

please help with any advise would be much appreciated.
