Replaced the blue slider in front passenger window on 2004 S60. Works except when window goes up it stops and then comes back down. I can close the window by sneaking up to the top but that's not a permanent fix.

Short history: I tried replacing the part with the window up, thinking it best not to operate the window. Could not quite get it as the ball on the metal arm would not quite reach. It was maybe within a quarter inch below the slider. Could not get that to go. So, I ran the window down maybe 6 inches and popped in the slider. All good except I gather it thinks it smashing something so it goes down. Just a guess but it seems like the safe thing to do if motor gets loaded.

CORRECTION: the ball was 1/4" ABOVE the slider when I tried to replace the part without moving the window, so it wants to push the window higher than it was.

Can I adjust the stop point?

Thanks,
