Thanks again for your inputs...

and again, it could be... but the car is parked in my covered garage, not used and not moved in two weeks, except when I decide to clean it. It was also cloudy and cool day that day.... it would be difficult to accept that it was caused by changes in temperature, pressure and weather. I even remembering opening the door the day before to take out one of the CD's from inside. So pressure could not have built up since it was night when I opened it and the weather next morning was cloudy- and it was covered parking.

I know how much heat and pressure can be generated inside the car if parked under very hot conditions, it can reach over 70degrees.

I dont beleive there where cracks on it since I cleaned it over the weekend where it was parked, and I would have noticed it if there was.

Dr.d, I am sure insurance will cover it, unfortunately this was the year I did not have it insured...

Funny btw, how each Nissan dealer have thier own price list... went to 3 already and it ranged from 12k++ to 17k++ only for the windshield. You may even be surprised who was the cheapest!

Replacement cost around 7k++, but this does not come with a defogger.
