The canvas was coming off the bottom of the rear window slowly over the last couple of years until it finally detached. So this summer I had the roof and window changed (there were some small cracks in the roof too). Anyways, 1 week after I get it back I put it down for the first time and the window pops. I take it back to the guy and he's surprised because it worked in the shop. He replaces the glass section again. THe glass was almost touching the back seat as it went down but it goes (I see him do it). About 1 week later, I put it down and it pops again! He swears the installation and parts used are good. The roof frame could be off somehow but seems strange, since the original window didn't break. Any thoughts on how to figure this out without risking breaking another window?

 

hey, welcome to the forum. what exactly is popping? The glass is coming out of the canvas "sleeve"? or the canvas is coming apart?

 

by "pop" I meant the glass broke...

 

I was told that you had to unzip the glass before you put it down.

For this reason I had a clear vinyl piece put in instead. I love it.

 

oh wow, that's crazy. Assuming all he did was replace the glass again, my guess is it will just break again. If it was a frame problem it seems like it would break even when he tests it in the shop.
Just brainstorming, it's gotta be some variable that changes over at least that much time. It could be temperature (getting too hot or cold), glue settling, the elastic stretching.
Maybe you could wait a week, then go have the shop try it again, and have everyone there watch for what may be smashing it.
