If the rear lower corner slide block is off the 'new' glass, you wasted your money. I have never had any luck with any product to rebond it to the glass. Buy a NEW window from the dealer!
If it is off, it is off because whoever adjusted the window did NOT set the down stop on the regulator. They let the window stop the regulator when the block hit the bottom of the door. You have to adjust the stop ON the regulator to stop the regulator 1st before the glass hits the door.
If you remove the outer chrome sill trim and the rubber, the window with block fits in the end of the door.
