Hello

The cars with headlight wiper have a diferent switch or diferent logo switch of those who have only the windscreen wipers?

Not that I was aware. What have you got? I have headlight wipers on a mk3 87 360, there are no markings on the stalk related specifically to this. They are only triggered by the windscreen washer. The only symbol is the wiper with winscreen and water jet.

It's that I have, and some information by Volvo Portugal is that the switch are diferente LOGOS or symbol's. The working process is with the withshield.
