<DIV>I second all of this with one exception. I'm not aware of any
alignment available for the quarter-light as the four bolts and screws pull it
down onto the top of he door and forwards into the corner. The only
adjustment after that is at the bottom of the long leg to control how the Q/L
tilts sideways to line up with the screen upright, which has little or no effect
on the operation of the drop-glass.</DIV>
<DIV> </DIV>
<DIV>The rear channel *is* adjustable, if it's not in close enough to the glass
that could be allowing it to tilt and/or come out of the front channel, but if
you press it in too far it makes the glass stiff to move. Chewed Q/L
channel runner is perhaps the most likely after that.</DIV>

<DIV dir=ltr> I can not ascertain the cause of the problem from
the pictures. My experience has been that the glass must be snug enough
in the guides so that it does not ‘rock’ as it moves vertically. </DIV>
<DIV dir=ltr> The front guide is part of the vent window assembly. This
is set first, set so that the vent window closes uniformly against the
windscreen. Once that is set, the rear guide is adjusted to snug the
glass just enough for smooth movement.</DIV>
<DIV dir=ltr> Once these are set so that the glass moves smoothly,
you can reduce the friction a bit by a few short shots of silicone in the fuzz
of the guides.</DIV>
<DIV dir=ltr> And, while the door is open, put a drop of oil on
each of the many pivots in the parallelogram linkage, and the winder shaft,
and a bit of white grease on the winder gears.</DIV><!--[if gte mso 9]><xml>
