Auto wiper problem RX400h

[Davey Blueeyes]

Okay so I have auto wipers and they are not auto wiping? They aren't wiping at all in fact in 'Auto' mode. Now the obvious place to start is the sensor (don't fancy messing about with that much!) but the manual says if the sensor goes on the fritz then it reverts to normal intermittent wiping (which I'd much prefer anyway) but it doesn't do that, it doesn't wipe at all in that mode. 

'High' and 'Low' settings work fine but it's a pain not having an intermittent wipe.

Okay, just in case anyone else has this problem, I detached the sensor from the windscreen, it just slides downwards to come off and the 'gel' pad had moved slightly. So I relocated back onto the sensor correctly, picked a few bits of grime off it, clipped it back on and I have auto wiping wipers again! The gel isn't perfectly flush, there's a few air bubbles, but it still works perfectly so all's good!

Had an issue on my is300h where the wipers were stopping mid screen and only way to get them to work was in fast speed on manual. After a bit of research on the forum I changed the wiper relay and that cured the problem. Bought two used from eBay for £5 and have kept the second in reserve just in case but have had no issues since. Not sure you have the same problem but a cheap fix if it is.

Once I'd cleaned up and reattached the gel pad as best I could it was golden! One think I noticed was that the cover was slightly loose, maybe it had been off before? But I clicked it back on and all is good
