Just finished conversion on this used 2012 v6 2500hd high roof. Love the van, very comfortable on long trips, springs are a little stiff for the weight i am carrying. have a problem with sliding door, will not lock or unlock electrically, works fine both inside and out mechanically. i am hoping some one on this forum has access to wiring diagrams so i can diagnose problem. need schematic for lock system and connector diagram that shows what pins are connected to what wires. Right now i have to reach around the cabinet to unlock door from right front seat, a real pain. any help would be appreciated. fyi i have already tried shimming connector housing for better contact, that did not do anything.
