The latch on the sliding windows are tightened by a set screw under the
latch. You will need to take a flat head from one of those removable
head screw drivers (called a 4 or 6 way driver) or some drill bits use
them as well. Then insert it from underneath and turn with 1/4 wrench
due to clearance. Be careful not to over tighten. I normally use
loctite.

If the whole assembly is moving then remove the set screw I just
described, a spring will fall out or may need to be wiggled, but it's
in there. Then wiggle the cover off and you will find two small screw
that hold a plat to the glass these may be loose. Carefully tighten
with philips, I use loctite here as well. Often I've found this plate
to be worn out and the screws can't tighten properly. You can order a
new one from the dealer or any of the on-line parts guys.

good luck

When I close the door it slides open a little.

Thanks,
