car had been sitting for about 3 weeks i went and started it up let run for about 30 minutes. i went back out and sliding drivers side door window was shattered. when i parked the car the temp was about 0 then it warmed up to about 25 and snowed about 5 inches, then warmed up and rained then went back down to 0 degrees. to the time when i started it the car had not been started or moved in those 3 weeks. the window was completely broke out on the outside of the seal. inside of seal it was shattered but still intact.

i think ice got built up on outside of the seal but got under the window, when it got cold again the ice broke the window
