Windshield Wipers: Description
Windshield wiper motors are either two or three speed design. Two speed systems park wiper blades in non-concealed or concealed (depressed park) positions depending on body style. All three speed systems park wiper blades in concealed position. Two speed motors are controlled by a third brush and resistor for low and high speed operation. Three speed motors are series-shunt wound for speed control. High and medium speed resistors are mounted in wiper switch.
