Hi

First of all has any one else had problems with the intermittent / rain sensor setting on the windscreen wipers?

When clicked into position nothing happens if I then click the adjustment it will wipe once then nothing.

If any one has any ideas or wiring diagrams that would be top notch .

Thanks

Turns out I need a new rain sensor which is behind the rear view mirror.

Thing is Skoda want £174.44 to fit and I cant find any place on the internet to purchase it my self

You can replace rain sensor, or you could just put a "normal" windscreen wiper relay (brown 377 or 389 one instead of grey 192 one). Then you do not need to touch rain sensor, and cost is far lower.

I replaced the auto relay on both Octavia and Superb. You get a lot more reliable intermittent wipe in place of dodgy automatic wipers, and wiper blades last much longer.

I use rainx and even at the lowest sensitivity the rain sensor would wipe the windscreen way too often. I even tried hacking the relay internals, but it made little difference.

Relay markings and colors

grey, with rain sensor, with/without headlight washer system (192)

brown, without rain sensor, with headlight washer system (389)

brown, without rain sensor, without headlight washer system (377)

If you still want to have rain sensor, then

Thanks both for your comments I think I will go with dieselv6's suggestion however as this seems the best idea,
