INSPECT FOR PROPER OPERATION: Figure 2
Check #1
With door window in full-up position, close door completely several times. Top of window glass should go behind clip (between clip and rubber seal) every time. If not, then adjust door glass rear up-stop block as described below to slightly lower top of glass so that it will snap under and behind clip. Do not over adjust or glass will not seat to top rail seals.
Check #2
Also, with door fully closed the window should open then close full-up with window glass inside of clip as above. If not, then adjust door glass rear up-stop channel as described below to move top of window slightly inboard.
