The water deflectors on all doors serve multiple purposes. The deflectors help to prevent the following circumstances:

More importantly, water deflectors help to seal the interior of the vehicle from the intrusion of vehicle exhaust.

All door water deflectors are perforated in order to assist the technician in accessing the interior of the door for service. In some cases, peeling back on the deflector will be needed.

Reseal the deflector if the deflector is separated at a perforation, peeled back, or removed from the door in order to prevent the intrusion of exhaust gases. When replacing deflectors which have been peeled back or removed, the adhesive on the door and the deflector from the factory will usually be adequate in order to re-adhere the deflector to the door. If additional adhesive is required, use a small amount of weatherstrip adhesive, such as GM P/N 12345096 or equivalent. If the deflector was separated at a perforation, use a cloth reinforced tape with a strong adhesive in order to secure the piece together.

Replace the deflector if the deflector is too badly damaged to provide a proper seal.
