rear window shattered
Anyone have any idea why when I put the rear defog on on my 97 escort the rear window shattered. I recently had the windows tinted but cannot imagine why that would have anything to do with it.

My dad has the 2 rear passenger windows blow out at the same time. Weird things happen to safety glass sometimes. Ever put a steaming hot glass in cold water, only thing that might explain it was the temp change.

Most likely because they used a very sharp steel knife, harder then the glass, to score the edges of the tint after it was place in the window instead of cutting it from a template and then placing it on the glass.
Drag a steel knife around a piece of glass scoring it, heat it on one side while the other side is cold and you can expect shattering results. One thing I would suspect, depending on the type of defroster, is the grid somehow got cut and only 1/2 of the window was heated and it stressed the glass especially if snow was placed against it. FWIW If the window was scored it probably would have shattered in the hot sun. If this was how the tint was installed.
Or it just happened. Sometimes it just does it because it is hot out, had it happen with my Aerostar factory smoked rear hatch window.

About 12 years ago some really bright
woman decided that she would use an automatic car wash to clean the snow off her car. As it was around 13 degrees at the time (pre windchill) shattered all her windows, got her wet and then when it stopped she iced over and a lot of the broken glass froze to her clothes. The owner of the car wash told us this and she said she was going to sue him
, he pointed to a posted sign stating not to do this and laughed. She's stuck with her own stupidity and bill, and I think the second one is the cheaper!

I had a friend that happened to when he turn on his defogger on his Dynasty. His broke because the defogger was stuck on and it over heated the window.
