GM Genuine Parts Windshield Wiper Motor Kits are designed, engineered, and tested to rigorous standards, and are backed by General Motors. Windshield wiper motor kits include a small electric motor that generates enough force to accelerate the wiper blades across the windshield. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
