Your vehicle has either a dynamic or non-dynamic (coast-to-park) braking mechanism on the windshield wiper motor. If you are replacing a switch, you need to know which type. This is all you need to know. Consult your Vehicle Owner’s Manual. For those who need to know how they work, read on… Dynamic brake: Essentially, when you turn the wipers Off, they stop when they reach their park position, but they get retarded electrically to bring the motor to a rapid stop. When you turn the wiper switch Off and the wipers reach the park position (left or right), the armature of the wiper motor is disconnected from the load and immediately connected across ground. The motor then functions as a loaded generator and develops a retarding torque that rapidly stops the motor. Non-dynamic brake: Essentially, when you turn the wipers off, they stop when they reach their park position. When you turn the wiper switch Off the wipers continue to run by a separate set of contacts mounted on the motor, unti
