  Q: What are the features and operation methods of the washer pump systems?

  A: Pre-1975 models have an electric Washer Pump system with a reservoir, pump, cam, and tubes, and pressing the washer button activates the Wiper Motor, which runs the Washer Pump. In 1975 and later models, a motor and pump are on the reservoir base. Pushing the washer button activates the motor, running the pump and wipers. The washers work when pressed; wipers run until switched off on the dashboard.
