The sliding door seems to pop out of the rear runner when being closed, I know it’s probably a stupid novice question but I just can’t work out why or if there’s something missing?!
Sounds as if it’s come off the runner, half way along is a small notch where you can pop the wheel back on
Try closing it with one of the front doors open, to let out the air pressure inside the van. Its usually much easier to close like that.
Half way along the runner is a notch where you pop the wheel out when you want to take the door off, look to see if it’s coming out from this notch
@sANDYbAY had a similar issue a few months ago and posted a good review of his fix with pics . Search his posts... Sent from my SM-A320FL using Tapatalk
