1999 Silverado Window Removal

[blakeaz33]

As others have said, the glass is installed with a urethane adhesive, much tougher than silicone. Dries with the consistance of rubber and when these are installed from the factory sometimes very little urethane is used and sometimes too much - the more the harder to remove. The best approach like the others have said is from the inside with a special utility knife, be careful to keep the blade off the glass because you will scrape the black band the back of the glass and it won't look right. Worst case is to price the new glass and then removal of the old is much easier. Removing auto glass like this is tought to do without breaking - Hope helps some.
