I love my auto wipers. They work perfectly, and the interval makes any necessary tweaks. They seem to always be doing what I want.
It’s been this way for 6 years of ownership.
Until the past few months, they stopped working at all. Only manual.
I began to research and found this thread.
I figured out that if the bottom edge of the sensor isn’t contacting the windshield- they don’t work.
While it was raining today I was able to press the bottom edge and sort of tune how well they worked. The tighter the push, the better they worked.
What I suspect is that those of you who are getting less than optimal, the bottom of sensor isn’t pressed.
Give it a try and report back.
