Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Description & Operation
A 2-speed permanent magnet windshield wiper motor is used. The 2-speed motor uses a 3-brush plate and switch assembly. Motor is operated at low speed (control selector in low position) by grounded Yellow wire brush and Blue wire on "E" series.
To operate motor at high speed, (control selector in high position), grounded brush and White/Orange wire brush are used to operate motor at high speed on "E" series. 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 interval wipers are available on all models. Intermittent operation is controlled by a variable resistor in windshield wiper control switch, which combined with electronic governor, allows a variable pause between wiping cycles.
On "E" series, wiper switch slides toward right. First position is intermittent, second is low and third is high. As control knob is moved to left of intermittent position, time interval between sweeps increases.
Electric washer system consists of a control switch incorporated into wiper switch, a reservoir and motor assembly, nozzles and connecting hoses.
On "E" series, circuit breaker is fuse panel-mounted for systems using slide control switch. Amperage rating for slide circuit breakers is 7.5 amps.
