2003 Chevrolet Trailblazer EXT wipers, windshield & visibility problems

On april 29, 2007, while my wife and children were preparing to go out to the store, the rear window on my 2003 chevrolet trailblazer shattered. No one was in the car at the time and there is no apparent cause for this event. Glass from the window went everywhere and even struck my 6 year old son in the leg. I have reported this to my insurance company and replacement of the window will occur on 5/2/07.

Tl*the contact owns a 2003 chevrolet trialblazer. The windshield wipers turned on and off automatically without using the switch. NHTSA campaign id number: 04v046000 component: visibility: windshield wiper/washer is related to the failure. The dealer confirmed that his VIN is not a part of the recall. The failure and current mileages were 160,000.
