When I asked this question: Rain sensing wipers not clearing often enough I wasn't sure the rain sensing feature was working at all.
I've since found that they do work, they just don't clear often enough, especially in light drizzle.
The car DOES HAVE a setting to adjust sensitivity, and I've tried ALL of the settings; the wipers don't clear often enough in any of them.
Since the car is only a couple of months old, I expect any parts/labor to be under full factory warranty, so I'm thinking of having the sensor replaced.
Question: would it do any good? Is there likely to be variation between sensors, and if so, might a replacement provide the improvement I'm looking for?
As an alternative question: do these sensors have "internal" adjustments which can only be made by removing covers, using tools, etc.?
