Windscreen cracked for no apparent reason

[Mark-in-Stoke 488]

I was tidying the car on Thursday evening when I heard a splitting (type) sound, I had a look around and didn't see anything wrong. I then moved around to the drivers side and carried on cleaning, it was then that I noticed a split in the windscreen 4" vertically up the passenger side and about 2" across the horizontal, making an arc.  Now get this the window on the outside is perfect, no chips or marks whatsoever, the crack itself can only be felt on the inside of the car!!!!

 

Any Ideas?

That's a tad concerning... There have been instances of them cracking when defrosting the car in the winter months.

Hmmm, just a nice warm evening when it happened and the car was stationary, really strange.

Mark - had you had the aircon on, specifically in the 'demist' position? How does the crack line up with the windscreen vent?

 

Merely a thought....

Keith, nothing was on mate, I'd just gone out to give it a quick clean or should I say removal of crap, the only thing it might have anything to do with 'maybe" would be how hot it had been during the day, that's all I can think of..

not very good and a worry. Hope you get to the end of what happened and why.

Put a picture up Mark, and I'll post a pic of the stripped shell in this area. There is a bulge in the metalwork around 270mm in from the pillar??

Hi Nigel, These are the pic's buddy.

Here you go Mark,

As you can see, there are rivet holes for the VIN plate and a raised seam. it looks like the raised seam may be your problem? When you get a new screen, you might want to ask the fitter to dress the seam down a bit?

Cheers mate, I'll see how close the crack is to that seam when they remove it and will ask them to dress it down a little too.
