The invention provides a vehicle door waterproof film with patches. The vehicle door waterproof film mainly comprises a waterproof film body, the waterproof film body is provided with at least one linear wiring harness hole through punching, the upper portion of each linear wiring harness hole is provided with a patch, the patches are welded to the waterproof film body, and welding lines between the patches and the waterproof film body are in an inverted U shape; a double-faced adhesive tape is attached to the inner side of the lower edge of each patch, the welding lines and the double-faced adhesive tapes form a closed loop, the double-faced adhesive tapes extend out of the left side edges or the right side edges of the patches by at least 2 cm, the extending parts of the double-faced adhesive tapes are release paper, the patches and the waterproof film body are made of the same material, and sound absorption cotton is attached to the lower surfaces of the patches and completely covers the linear wire harness holes. The vehicle door waterproof film with the patches has the advantages that the double-faced adhesive tapes are additionally arranged, the double-faced adhesive tapes and the welding lines form a closed space, the patch covering position can be waterproof and dustproof, meanwhile, the patches and wire harnesses are fixed through the double-faced adhesive tapes, shaking of the wire harnesses along with a vehicle is weakened, abnormal sounds in the driving process are reduced, and the service life is prolonged.
