Just got back from Tesla service center.
USCBucksfan is correct. The tech said that since the USS were removed Tesla relies on camera input exclusively, and that is why the wipers are always active. He said as the new camera programs are updated there may be a change allowing the wipers to turn off, but he doubts that will happen.
”Keep the ‘box’ where the front cameras are located meticulously clean.“ I cleaned them last night, but in the dark I apparently missed a small debris blob, enough to send a blurred image to the camera which interpreted the blob as rain, forcing the wipers on.
He suggests not using chemicals to clean the area, and a fiber towel afterward. On the drive home from the service center all was well.
That smells fishy. I don’t believe USS was the rain sensor. We have an M3 with USS and an M3 without USS and have seen no difference in the auto wipers which are working fine and not going crazy full on for no reason.
