W109, 3.5 window switch must be misconnected

[werminghausen]

For the driver window...when I operate the switch pressing front part is lowering the window..pressing the rear part is closing the window.
I think this is reverse. How do I need to change the wires in order to be correct (pressing front = closing, pressing rear of the toggle= opening)?
There are 3 wires in a triangle location : which ones do I need to swap?

Anyone?

It sounds like wires were reversed on the regulator itself. If you want to reverse them on the switch itself instead, you'd probably need a multimeter to verify the proper wires.
