Three problems related to windshield have been reported for the 2000 GMC Sierra. The most recently reported issues are listed below.
I was driving at a speed of 60 mph with all windows shut and my air condition on when my drivers side ext-cab window just blew right out of the truck. The latch that holds the window shut hit one of the kids in the hand and ended up in the passenger side pocket. The window hit the side of the truck then ended up shattering in the middle of the road with traffic trying to avoid the broken glass and me pulling of to the side of the road wondering what happend. That could have caused a major accident, and the latch could have caused serious injury to a child if hit in the face. Thanks jeff.
Rear windows have been replaced several times due to wind noise. Nlm.
Rear glass frame cracked from factory and replacement failed twice and had to be replaced with flat glass not the sliding glass I ordered from the factory . Both side quarter windows had wind noise and had to be replaced. S.
