After completion of the repair check door glass/seal wipe pressure. The wiping area of the seal should exhibit a very light but consistent pressure
against the glass. If seal loading is determined to be excessive, remove the panel and reduce the seal pressure by the door inner panel as shown in
Figure No. 5. Re-check the seal action after door panel installation.
