1987 Chevy S-10 Blazer Window

Hey Jeff, Good morning, you will need to take off the inner door panel which means the door handle, window handle, armrest, and anything else in the way. Inside the door shell there should be metal tracks that should have notches cut out for you to slip the rollers on the regulator[crank gear] arms into and get them back into the tracks. You may have to take the regulater loose from the door to help get them back in line. It's a pain and you work bind alot but you can do it if you are patient! Key word "PATIENT". Have done this on my old chevy truck "71" but think they will be close as to how they are set up. Hope this helps you to get it straightened out :D

Take off the door panel and see where it is off track. I suspect one of the track braken came loose either broken or the bolt came out.

Replace the screwdriver with a small piece of wood. It will save a broken window
