What Causes the Wiper Blades to Shake on a Regal?

[DeGriffin]

Here are the specific reasons why the wiper blades on a Regal may shake: Aging and hardening of wiper blades: The actual cleaning function of the wiper blades is performed by the rubber strip that contacts the glass, while the rest consists of the housing and pressure components. The rubber material of the wiper blades is directly exposed to the air and faces various harsh weather conditions, leading to rapid aging. Typically, after two to three months of use, issues like noise or shaking may start to occur. Improper installation: If the wiper blades are not installed properly or if the wiper arm is deformed, shaking may persist even after replacing the wiper blades, which is often due to this reason. Incorrect positioning: If the wiper arm and pivot shaft are not securely fastened or are positioned incorrectly, it can result in poor contact between the wiper blade and the windshield, causing an improper angle and leading to shaking.
