Technical Window electrics

I've had a look in the downloads but can't spot it... looking for a wiring diagram for the front windows, specifically passenger side. New switch and still it only goes down. From other side (drivers), window goes up and down so just trying to trace the wiring. Any help appreciated. I've plugged in EMS and it also doesn't show up switch being PRESENT when pressed.

Thank you.

All sorted. Once I understood what it was doing, thanks to Deejays diagrams, I broke the switch apart, tested the resistors, understood how it worked and since it only works in the mA range, all it turned out to be was a dirty contact.

Be warned, the previous wiring was plus/minus 12V for up/down on a 4 wire pin. On the 250/290, it's only 3 wires, signal, ground and light. Don't buy the wrong switch (it still has 4 pins but only 3 function, the circuit board inside though is different).

Excellent outcome and return advice. Cheers!
