If I'm not mistaken (which I very well could be), It takes 6-8 'sweeps' of the wipers to put an AWD car into AWD if it was previously in RWD. Not sure if this is the same? Or are you saying if the wipers are left in the intermittent mode (maybe lowest setting?) there is an actual external sensor that detects water that would automatically start the wipers?
I know the 'humidity sensor' is inside the vehicle and relates to HVAC actuation, specifically the front/and maybe rear defroster activation while in auto climate control mode... hmmm.....
