At Sprague Devices, we rate our wiper motors by stall torque, which is expressed in Newton meters (Nm). The size of your commercial vehicle’s wiper arms and blades can determine the best wiper motor for your application:
8 Nm: recommended for small wiper arm and blade combinations of 16” (400mm) and under.
12 Nm: recommended for wiper arms and blades in the 16” – 20” (400mm – 500mm) range.
30 Nm: recommended for wiper arms and blades in the 20” – 28” (500mm – 710mm) range.
38 Nm: recommended for when one motor drives multiple arms and blades or for wiper arms and blades of 28” and longer.

Your windshield wiper motor is first installed on the firewall. It is then connected to your system of rods, arms and joints known as the wiper transmission. When you switch on your windshield wipers, your wiper motor spins and rotates a crank arm, moving the wiper blades across your windshield to remove rain, dew, snow, dirt, sand, and/or other debris from view.
The wiper park switch, often built into the wiper motor gearbox, controls where your wipers park on your windshield. This park switch ensures that your blades start and stop in the correct resting position when you turn off your wipers. You can activate the switch by powering the wiper motor until the wipers reach their preferred park position.
If your wipers are stopping in the wrong position, this is a sign of your switch going bad. Contact us today to see how we can best replace this part for your commercial vehicle.
Under normal conditions, a wiper motor should last a vehicle’s lifetime. However, there are several reasons why a windshield wiper motor stops working:
Frequent use during wet or dusty conditions
Regular use of wipers on a dry windshield or across extremely dirty surfaces
Switching wipers on to clean a frozen snow and/or ice-covered windshield
Wipers not starting in park position
Grease drying up which causes rapid motor wear
Faulty parts within the motor or wiper system (blown fuse, bad relay, failing connectors, etc.)
Under normal conditions, we recommend changing your wiper blades every six to twelve months. Environmental and seasonal conditions can lead to longer or shorter replacement intervals.
