when using wipers in auto mode, they seem to change speed drastically.......is this normal ? notice at highway spped or around town.
thanks

They sense how much water is on the windshield.
The sensitivity can be adjusted by turning the knob up or down.
There is a white line on the knob...down towards the floor...makes them less sensitive...and obviously turning UP makes them MORE sensitive.

I sometimes have to adjust mine one or two clicks either way...depending on the actual rain fall, to get them JUST RIGHT.
