The Nissan Sylphy's wiper may keep spraying water non-stop due to the spray switch contacts sticking or mechanical jamming causing the contacts to fail to open. Below is a detailed introduction to the car wiper system: 1. Main Components: The electric windshield wiper is driven by a motor and generally consists of the wiper arm, wiper blade assembly, rubber blade, blade holder, blade support, wiper arm spindle, wiper base plate, motor, reduction mechanism, drive linkage, drive linkage hinge, wiper switch, and wiper switch knob. 2. Working Principle: The left and right wiper blades are pressed against the outer surface of the windshield by the wiper arms. The motor drives the reduction mechanism to rotate, and through the reciprocating motion of the drive linkage system, it moves the wiper arms and blades left and right to wipe the windshield.
