Does anyone know how to remove the passenger door vapor barrier behind the panel? I removed the mounting bolts, electrical connections, etc., and pulled the barrier away to ensure it was not a glue issue. It seems to be attached to a cable or white plastic piece (?) at the door latch end, everything else is good to go. I have perused this site and VWVortex to no avail, googled, checked online manuals with no luck. Any help would be much appreciated.
