It was shutting ok before I put the rubber on. The van is brand new, just strange how one side is fine the other not?Try closing the door with the window open, if the door shuts no problem then it’s almost certainly the fact that the air pressure in the van is the cause
Had the same with my last van, not sure why they seem to do this!!I had this. Passenger side was good, drivers side was a bit of a pain! The seal got ripped off by the jet wash a few weeks ago and the door has been fine since.
I just got used to closing the door twice every time I got out! Haha
