Same issue with mine. I have the setting on in the vehicle/wipers/rain sensing setting on the center screen, and if my wipers are set at 0/A bottom position it does nothing. I read that is normal. But even if I put it on the single rain drop position the wipers perk up about an inch prior to the first wipe and then stay on as a slow intermittent wipes until I turn them back to the off 0/A position. As I up the rotations on the stick it has less delay between wipes, but nothing auto or rain sensing happens. I tried running a sprinkler over the windshield this morning, tried all positions of the rotational stalk. Nothing changes unless I rotate the stalk, only slower or faster, with and without water on the windshield.
