Windshield Wipers: Description

One and two speed permanent magnet windshield wiper motors are used. One speed motor uses a two brush plate and switch assembly while two speed motor uses a three brush plate and switch assembly. On two speed motors, when control selector is in low position, grounded brush and white wire brush are used to operate motor at low speed. When control selector is in high position, grounded brush and blue wire brush are used to operate motor at high speed. When control selector is moved to park position, motor will continue at low speed until park switch lower contacts open, stopping motor in park position. Optional intermittent wipers are available on 1973-74 "F" models. For normal operation on this system, turn wiper control knob to right for low or high speed. For intermittent operation, rotate wiper control knob to left. The more knob is rotated to left, the greater the time interval between wiper blade sweeps.
