FIXED! One-touch driver window opening - doesn't work

Weird, I just found out that one-touch opening of driver's window doesn't work. Closing - works. Passenger door - works (opening and closing). Driver's - only one-touch closing works. Opening works as usual, while you are lifting the switch up.
I checked with PA Soft 1.4 - the checkbox for autoopening is set. I removed it, when set back - nothing. Changes with passenger door are instant: I can see that I am turning auto-opening/closing. Auto-closing for driver's door is also "turnoffable". But auto-opening - nah. What's wrong?
FYI, This doesn't change anything

I played with INPA, tested window regulator. If I send a command by INPA the window goes up and down with no problems. Moreover, I found a screen where they draw states of the switch ("open" - "close"). Thus, when auto up/down occurs on working side I see that both of these states are set (two black dots are drawn). Same happens when I roll up the driver's window by one touch - both dots become black for short period of time. But when I try to roll the driver's side window down by one touch I see only one black dot at "open". Seems to me the issue is in switch.... Thank God I can get it for just $35 from www.bmwmercedesparts.com

I believe you can use INPA to simulate the button press. Try it and see if the window responds properly?

I'm having the exact same problem with my driver's side window. I had a power glitch in the car and had to reinitialize both windows. The passenger one works up and down now, but the driver's side only does auto-down and not up. It's driving me crazy. Keep us updated if the new switch makes it work.

FIXED. Price - $0. Just disassembled the switch and cleaned contacts. That is it.
Plus, I've done modification for one-touch vent windows closing, by using shadowcatxx87 DIY (thanks a lot, man!):
http://forum.e46fanatics.com/showthread.php?t=783164
Coding I've done by P.A.Soft 1.4.0.
Some pics:







P.S. I found out that one of the buttons is cracked (plastic). Nothing critical (yet), but would like to replace the plastic part of the button eventually. If someone has non-functioning window switch (regardless sedan or coupe, driver's or passenger's side), I'd be happy to get it from you for cheap.
