My rain sensing wipers in my GenII Luxury was giving me the problems as regardless of how I set the sensitivity, they reacted the same
I spoke to my Dealership and they told me how to reset them.
Get in the car
Make sure wipers are in Off mode
Turn the car on to ACC
Turn then to auto and off 5 times
Off - Auto
Off - Auto
Off - Auto
Off - Auto
Off - Auto
The wipers will pause for a second and then wipe to confirm they are reset
They now work perfectly and when I put them on the lowest sensitivity they don't wipe a million times when it's spitting!!
