A seal for a vehicle door. The seal includes a lower seal member structured to be mounted to a lower vehicle door portion and an upper seal member structured to be mounted to an upper vehicle door portion. The upper seal member sealingly contacts the lower seal member when the upper vehicle door portion is mounted to the lower vehicle door portion. The lower seal member includes a projection structured to abut a portion of the lower vehicle door portion when the lower seal member is mounted to the lower vehicle door portion, so as to prevent a movement of the lower seal member and resulting misalignment between the upper and lower seal members during movement of the seal members into sealing contact with each other.
