What's the reason for the windshield wiper not moving?

[Hector]

The following is a related introduction to the windshield wiper not moving: 1. Identify the model: First, refer to the vehicle manual to determine the model of the wiper being used. 2. Connection method: Pay attention to whether the connecting rod is correctly attached to the wiper arm. Some arms are fixed to the arm with screws, while others use a snap-lock mechanism. 3. Check the rubber: Lift the wiper and feel the cleaned rubber with your fingers to check for any damage to the wiper and the elasticity of the rubber blade. If the blade is aged, hardened, or cracked, the wiper is faulty. 4. Check the speed: During testing, set the wiper switch to various speed positions to check if the wiper maintains a consistent speed at different settings. Especially in intermittent mode, observe whether the wiper maintains a steady speed during operation. 5. Check the wiping condition: Inspect the wiping condition and whether the wiper arm swings unevenly or misses spots.
