Why is my windshield wiper vibrating?
Car: Lexus CT200H, ZWA10L-AHXBBW (2016)
Ever since I purchased the car back in 2021 my windshield wiper on the driver’s side has been having some major vibration at the bottom part and it has never made any annoying sound. First, I thought it was because of the non-OEM wipers from Bosch that were put on the car, and I didn't think any more of it.
Now, 5 years later, I have installed the OEM wipers on the car, and it still vibrates the same way on the driver’s side. I thought maybe it isn't tightened enough, but I have had my windshield replaced a couple of times, and that has never changed anything. So unless the Lexus dealership where I replaced my windshield has not done the tightening correctly multiple times I don't think it's the tightening.
The issue happens even when it's raining so it should not be about the windshield being too dry.
Now I am really stuck on this issue, trying to figure out what is causing it and how to fix it.
