I work for an auto glass company, and this can be done, but you will need the right adhesive and a steady hand to cut down the old glass/glue.

If your upper door glass is shattered, the replacement can be done without power tools. You will need to shave down the adhesive and remove all debris from the area. You can use an automotive grade urethane adhesive such as Sika 220/SikaCool/ or a Dow equivalent to properly install the glass.
