What is mechanical windshield wipers?
Wipers may be powered by a variety of means, although most in use today are powered by an electric motor through a series of mechanical components, typically two 4-bar linkages in series or parallel. Early wipers were often driven by a vacuum motor powered by manifold vacuum.
What is wiper mechanism?
This model shows an application of a four-bar mechanism that converts the rotation of an electric motor into the sweeping motion required for a windshield wiper mechanism. The friction between the wiper blades and windshield is accounted for in the Bearing Friction component.
How does the front wiper motor and linkage work?
The front wiper motor and the wiper transmission mechanism (linkage) are installed below the windshield inside the cowl panel. How the wiper system works: the wiper switch sends the signal to the control module. The control module operates the wiper relay that sends 12-volt power to the wiper motor.
How are windshield wipers controlled by the motor?
In order to move back and forth across the windshield, the windshield wipers are controlled by the windshield motor. When you activate the windshield switch on your turn signal indicator or other control arm next to your steering wheel, it sends a signal to the motor and operates the wipers at different speeds and duration.
How does the park switch on a wiper motor work?
A scan tool also allows an active test, which means a wiper motor can be activated from a scan tool. The wiper motor is a DC (direct current) 12V motor that includes a set of gears and a park switch. The park switch allows the motor to stop when wipers are positioned at the bottom of the windshield. This position is called “park position.”
Where is the front wiper motor located on a car?
Wiper motor. The front wiper motor and the wiper transmission mechanism (linkage) are installed below the windshield inside the cowl panel. How the wiper system works: the wiper switch sends the signal to the control module. The control module operates the wiper relay that sends 12-volt power to the wiper motor.

What are the symptoms of a worn out wiper motor?
A clanking noise coming from the wiper motor area when wipers operate is one of the early symptoms of a worn-out link or other component of the transmission. Another symptom is when one of the wiper arms feels loose or swings too far. Mechanics use a special wiper arm puller tool that you can purchase or loan in some parts stores.
