Hey guys, so the upper part of my driver window (the non-moving part) shattered completely RANDOMLY. The car has been sitting for a few months in my driveway while I'm at school and the door hasn't been opened for a few weeks. We've ruled out vandalism, etc. which is already doubtful since it's just the upper part and there is no apparent impact damage, just a uniform shatter!

Does anyone have any ideas what could cause this? Also where can I source this window piece? Is it easily removed from a complete svx door or should I just replace the whole door?
