Area D: Over Sill Plate

1. While an assistant directs water along the beltline molding, inspect for water entering from over the plastic sill plate. Figure 10.

2. If water is entering over the sill plate, remove the door panel and check that the plastic sheeting Butyl sealer is pressed firmly against the door frame. Also, check that no gaps are present between the sheet metal and the plastic.

3. Confirm that the door drain holes are draining properly and are not obstructed.

Note:
If Butyl sealer is hard or non-pliable, new sealer will need to be applied to the plastic sheeting to properly seal water leaking from these areas.
