What to do if the left bottom of the wiper is shaking?

[SanRose]

This is caused by the excessive friction coefficient between the glass and the wiper blade, which can occur in almost all car brands. Three recommended solutions: 1. Replace the wiper: Choose a wiper with good rubber coating, not necessarily the most expensive one, to effectively solve the shaking issue at the left bottom of the wiper. 2. Glass coating: Applying glass coating can also resolve the majority of wiper shaking problems. 3. Wiper anti-shake agent: If the problem persists, apply "wiper anti-shake agent" on the wiper blade, which can directly address the wiper shaking issue.
