Condition
Some owners may comment about water dripping from the top left corner of the driver side windshield or water leaking from between the moldings at
the front of the driver side door area below the instrument panel.
Cause
Condition may be due to a void in the sealer above the B-pillar. This may allow water to enter the quarter panel at the top. Because the rear of this
channel is higher than the front, this allows water to channel forward and come out at the above locations.
Correction
Reseal the roof to B-pillar surface using the following Service Procedure.
