Re: passenger sliding door problems
Well, it's been almost a year since this original post and it took a rainy camping day this year for me to tackle it. On this trip we had also experienced a sticking interior door release button on the other working door, so it was time to take action.
My issue turned out to be the cable from the exterior door handle. There was too much slack in it--the handle did not 'pull' enough cable to complete the rotation of the cam system. Being out in the Canadian wilds I wasn't about to attempt to modify the cable itself by shortening it, so I simple took two medium zipties and filled the space between the cable end stop and the cam slot. Problem solved.
The sticky interior release button was easy--disassemble, clean and lube with petrolium jelly.
It really pays to travel with a tool kit including duct tape, zip ties and lube of some kind.
Thanks to all who commented on this thread--especially for the photos
