Where is the wiper node located?

The wiper node is located at the connection point between the wiper arm and the wiper blade. Its function is to help determine the position of the tires, avoiding them from pressing against solid lines or encountering potholes and stones on the road. The wiper is a blade-like structure installed in front of the windshield, consisting of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Its purpose is to clear rain, snow, and dust from the windshield that obstructs the driver's view. The steps to replace the wiper are: 1. Lift the metal wiper arm away from the windshield and hold it steady in a position perpendicular to the windshield; 2. Press the tab and remove the old wiper blade, separating it from the metal arm; 3. Insert the new wiper blade, gently rotating it until the hook snaps into place and is secured; 4. Return the wiper to its position on the windshield.
When I first bought my car, I didn't quite understand the term 'wiper node' either. Later, I realized it refers to the connection point between the wiper blade and the wiper arm. Basically, all cars have it positioned slightly below the center of the windshield, but the exact location depends on the vehicle's design. Some Japanese cars have the node more towards the center, while European cars tend to place it closer to the edge. If the wiper blade isn't properly aligned with the socket during installation, at best, it might leave blind spots when wiping, and at worst, it might not clean effectively. I once encountered misalignment when changing wiper blades myself, and the blade suddenly came off while driving on the highway, which gave me quite a scare. I recommend checking the original position and height before installing new blades, and it's safer to have two people work together on the task.
