I am having the windshield replaced on my 1996 S600.
The glass shop wants to know if I have rain sensing wipers. I told him I did not know. I have had the car for years and did not know this feature existed.
There is a large black type of knob on the drivers side of center near the rear view mirror. Also, the windshield has a portion there that is small black dots.
Can anyone tell me which windshield I need.

Thank you in advance......Bill
