DOOR PRIMARY SEAL LEAKS
Door-to-body primary seal leaks may occur generally for one of two reasons. Either the seal is not seated correctly to the body flange and does not
follow the door sealing surface or the door itself is out away from the body such that there is not sufficient contact with the seal.
Repair Method:
With the door closed, inspect for seal contact with the door. If the problem is one of improper seal contact due to misalignment with the door surface,
pull the entire seal off the body flange and reinstall as follows: Position the joint in the center of the rocker and install on flange working forward toward
hinge pillar; continue around door opening using care to seat the weatherseal securely onto the flange, particularly in the corners. When the seal is
completely installed, go back over the entire length and make sure no material has pulled off the flange. If the leak source is determined to be a result of
too much gap between the door and body; door adjustments will be required to close up the gap. Reinspect and road test after corrections are made.
