Wiper motor for M21 RR 71?

[torbsim]

Hi everyone, I'm wondering whether my 1971 M21 RR has a 2-speed or 3-speed wiper motor?

The documentation doesn't provide any information, and the body manual says 2 in some places and 3 in others.

I think the 3 stands for Satellite Premium models, but I'm not sure.

What does your experience tell you?

Thanks
Ben

What does the one you have look like?

If you have the switch is it 3 or 4 position?

So I can only adjust the button by 2 levels, and I would say that means only the 2-level one? Right?
