Back window go BOOM!!

Wow that is really strange...do you think that maybe you parked too close to the garage door and the arm of the door came down onto the glass as you walked in the house??

ics:

I didn't do it, I swear!!!

:bill:

It happens. A coworkers Explorer did that in his garage when it had a 200 thousand miles on it. No explaination other than it had to do with temperature and differing rates of thermal change with glass, air and metal. I dunno, maybe something binding in the mounting hinges?

we used to have a mini soft top (with glass in the hood) and it was a relatively common problem, i think its to do with different layers in the glass having different thermal properties and as one expands/shrinks it does so at a different rate to the one next to it - hence SMASH!

Click to expand...

That's possible. I'm sure it's the thermal properties of one not mingling with the other very well in any case. :beer:

Does the rear hatch glass even have layers? The front laminated windshield has layers, but tempered glass usually goes boom when there is a nick on the edge somewhere, where stress is concentrated. I had a tempered glass cabinet door shatter on its own a few minutes after I set it on the floor on its lower edge.

i doubt it is because of temperature. the little connector for the defrost came off the glass on mine, so a few days ago, i drove to the shop and removed the back window, and put it on a workbench, and proceeded to solder the connector back on. nothing happened to my glass, and BTW you cant solder metal to glass, you have to glue the connector back on and then use a defrost repair kit and coat the edges so it makes contact.

sorry for the off topic, but my glass literally went from outside to the workbench, it did not have time to get warmed up.

My neighbor's back glass shattered one summer in his back yard. The heat was 100 degrees plus but no one was around when it shattered. We figured it was due to the heat.
