Figure No. 4 - Checking Window Regulator and Left Arm
4.
Window Regulator - Check window regulator and left regulator arm for any binding (see Figure No. 4). Marks will be visible where the regulator
arm and sash have contacted. If left regulator arm is catching on the window sash, carefully bend regulator arm as required. Check the meshing of
the regulator teeth. An overly tight meshing will cause unnecessary binding and the regulator assembly should be replaced.
5.
Window and Sash Assembly - Remove glass and sash assembly for inspection. This can be accomplished by removing the four bolts that connect
the sash assembly to the regulator arms.
Figure No. 5 - Centered Sash on Glass
-
If sash is not centered on glass, remove the sash and center it on the glass assembly (see Figure No. 5).
-
Remove any excess sash filler at the ends of the sash assembly.
