My uncle told me I need a new wiper delay module to fix my wipers. Autozone dosen't sell just the delay module, so I bought the whole new motor. They told me that the delay module comes with the motor. When I looked at the old motor still on my car, there some sort of a black box that screws to the back of the motor that the wires snap in to. The new motor I bought does not have this, but it has an obvious place to screw it on. Is this the delay module, or is the delay module built into the motor??????
