car washes enters the lock cylinder through a hole in the outside door handle housing where the cylinder retaining panel snaps into the housing. This
water can freeze in cold weather, thus rendering the lock cylinder inoperative.
To correct these conditions, it is necessary to replace the outside door handle assembly with a redesigned handle assembly (P/N 15686155 LH or
15686156 RH). To stop the door handle spring from moving, a rib was added to the bezel (figure 1) and a piece of foam tape was placed over the hole to
prevent water from entering the lock cylinder (figure 1).
