maybe im just stupid, but i cannot figure out for the life of me what the windshield wiper settings do.
i know the lever will adjust speed as you move it up the notches, and a down bump is for a quick wipe. but what is the rotary dial do?
i seems like it has almost no effect on anything. and sometimes when its set to high the wipers will randomly start wiping like crazy....
granted, i live in So Cal, so rain is rare, but id like to understand this before we get our downpour (all 4 hours of it) this coming "winter"
