Problem

Action

The rear striker is too far inboard.

Adjust the rear striker.

The front of the door is too high in relation to the opening.

Inspect for witness marks on the inside pockets of the locator holes. Adjustment of the lower roller bracket UP lowers the door.

The door header clearance is too small.

Remove the roof rail weatherstrip and close the door. If efforts improve, reform the header for more clearance.
