How to Align the Wiper Linkage Rod When Replacing It?

[DeJasper]

Method for aligning the wiper linkage rod during replacement: 1. Remove the wiper; 2. Turn the wiper switch to the first gear or push it upward once to let the wiper operate automatically and return to its original position; 3. Reinstall the wiper after it returns to position. The wiper is a blade structure installed in front of the windshield, consisting of a motor, reducer, four-bar linkage mechanism, wiper arm spindle, and wiper blade assembly. Its main function is to clear rain, snow, and dust that obstruct the view on the windshield. The power source of the wiper comes from the motor, which is the core of the entire wiper system. The wiper motor uses a DC permanent magnet motor, and the motor installed on the front windshield is generally integrated with the worm gear mechanism. The worm gear mechanism serves to reduce speed and increase torque, and its output shaft drives the four-bar linkage mechanism, converting continuous rotational motion into left-right oscillating motion through the four-bar linkage.
