    Old glass? probably not. Never heard of glass being old causing it to break. I've slammed the doors on old stuff from my 69 nova to 31 model A Vicky and never broke one. Tempered glass and non tempered.

    Pressurization of the cabin might be the cause, but I've never seen a K5 sealed up so well that air can't escape when the door is shut. Mine leaks air like a sive. It could be that the gate glass was in a bind in the top and the slamming door was enough movement to tweak the glass. The back glass is tempered so any flexing will cause it to shatter into a million pieces. I know mine will roll up in the top weatherstripping funny sometimes, but being a manual window I feel the resistance and see it get stuck. A power window might just keep cramming the glass in the top eventhough it might not be going in straight.

    A lot of times the window regulator mechanisms rust up in the back windows, more than likely it wasn't being supported very well.

    I've busted a window in a door when it wasn't all the way up, but with the window up all the way, slamming it as hard as I want won't break it.

    cold === brittle!??

    When I worked at the junkyard,we would sometimes smash out the rear windows of a car we were scrapping,so we could fill the interior with more junk like bumpers and doors of other cars,etc--many times in the summer we would hit the widow real hard with a tire iron,and it would just bounce off!--a few times I could not beleive how hard we had to hit it before they would break!:confused:

    But in the frigid weather in the winter,usually it only took a slight tap, and POW!-the window would practically explode!--I think the extreme cold makes the glass more brittle,and also hardens the rubber gaskets enough to prevent any "cushion" effect,it wasnt hard to break a window you were trying to remove for a customer too,unfortunately....we went thru 3 windows before we got one out in one peice on 3 chevy impala's one 10 degree day!--the guy who bought it called the next day--he broke it trying to put it in,and was looking for another one!...:doah:
