If you mean the window indexing feature, it's easy to fix.
Just lower the window and hold the button down for a second or two. Then raise the window, and hold the button up. You'll need to do this for both windows. It's explained in the manual too.
since installing my valet, my driver side window indexes about 1/3 "
repeatedly, no matter what i do with the window switch weather car on or off. even after i removed it, now i have to go to the dealer..
oh, and the driver door does not work either, i have to open manually from passenger side
