I've just done mine but with the door card off as I had to adjust the limit height also.
Screw has a locking nut around it so you need to free that off first. This should be possible with a socket with the door card on. I used a ring spanner with the card off.
Turn the screw (flat blade) clockwise to move the bottom of the guides out which moves the top of the window in towards the rubber. Screw on the right will give adjustment to the right hand guide, left adjusts the left. Then tighten locknut up.
