Another solution occured to me. Perhaps the installers put the new gasket
in upside down. I think the gasket has a slight taper towards the top.If it
is installed upside down, the taper will be towards the bottom.Just a
slight taper it is.This mistake can happen. Maybe check for molding marks
at the center of the gasket. See if they are at the top or bottom. Then
compare this with any other or the vanagons in your gorcery store parking
lot.Better not install a new chrome locking strip, or you will want a new
one in all your windows.
