The wiper switch stalk is part of a range of electrical appliances that function to assist the driver of the car and to enhance the overall driving experience.
The wiper switch stalk is generally mounted on a car's steering column with the primary function of switching on/operating the car's windscreen wipers. The wiper switch stalk will usually contain the controls to activate the windscreen washer too.
It is designed to allow the driver to easily operate the windscreen wipers without having to remove their hands from the steering wheel. The driver can decide at what speed the wipers move, usually from a choice of three speeds, depending on the weather conditions. The driver can operate the wipers by selecting the desired speed on the wiper switch stalk. This activates the wiper motor switch, which operates with a wiper motor relay. When the wiper motor switch is activated by the driver, this sends an direct electric current (provided by the car's battery) to the wiper motor. The wiper motor is what generates the force to power the wiper mechanism.
The wiper stalk switch is generally maintenance and problem free although like all components can be prone to wear and tear and accidental damage. This can include electrical faults due to burnt out switches of short circuits. Replacing this part with a new wiper switch stalk will give you a part that is compatible with your vehicle.
