Hello Listees:
I need to replace a broken window on the sliding door of an '85
Vanagon.  It is the sliding window that is broken, not the fixed
one.  I have an entire window assembly, but I assume it is easier
to replace the individual pane, as opposed to the whole thing  (I
have replaced a rear quarter window before, but I don't have a
helper this time, and Hurricane Rita promises a lot of rain this
weekend).  In the past, I have removed this window pane by using
one or two scissor jacks to vertically spread apart the window
frame enough to remove the glass, but I ended up permanently
bending the frame (this is with the window frame assembly installed
in the door).  I think I removed the plastic channel guides on the
lower window channel, but it was still a very close fit.  I would
prefer not to damage the window frame this time.  What is the best
way to replace this sliding window pane?  Do I have to remove the
entire window frame from the van?  As always, thanks in advance!
