Auto body repair & detailing: TOYOTA COROLLA, butyl tape, glass run

Question
I AM CONCERNING ABOUT THE RUBBER THAT AROUND THE WINDOWS, IN THE WINDOWS DRIVER THE RUBBER IN THE UP SIDE NEAR TO MIRROWS IS SEPARATED (DETACHED) HOW CAN I STICK IT?? OR REPLACE IT, THANKS A LOT FOR YOU HELP ME.

Answer
Not sure what year your vehicle is, but over time and weather, a glass run (this is the technical term) can shrink.  Roll dowm the window all the way. Pull the glass run away from the door frame only. Heat the glass run with a hair dryer if available. You should now be able to stetch it longer. Apply butyl tape (available at your local glass shop) to the inside if the glass run and reinstall. This will help keep it in place. Hope this helps
