Does anybody know the pricing for the W203 rain sensor and where to buy this thing?

if you are retrofitting this item, make sure your windsheild has the necessary lens installed to hold the sensor. Programming will be required.

Along the same lines....

How can I tell if its working or not? I was expecting to see a variable delay between wiper swipes but it always seems to be about the same (approx 5 seconds between swipes). Does it vary enough to be obvious? Mine has always been the same, so I don't know what's "normal".
