I searched for this problem, but came up empty handed. Does anyone else have a slow wiper speed in the fast setting? This is my third Infiniti and the G35 has the slowest fast speed wiper setting. During heavy rain I have to slow down so I can see better. I also use rain-x to help for this problem.

 

you can turn the little dial on the side to make it go faster...also i believe i noticed that the wipers seem to go faster when going at a faster speed...or maybe it was just me ...lol..
