Cleaning them with a small wire should do the trick.
I also checked the seal around all the windows - found a couple of places where they cut the seal short. Filled the spot with black RTV.
Found this on the internet:

WEEP HOLES – WHAT ARE THEY?
By John McHale
Weep holes are on many type of RV SIDE windows. To my
knowledge no weep holes are on front RV windows. They divert the water from the
inner slide windows that seeps under the rubber molding and are on the bottom
of the slot (trough) where the slide window slides. On the outside of the
vehicle, the holes can be seen below the non-slide windows. They are slots
about an inch long and about as wide as the lead in a lead pencil. Usually,
there are two or three per window. The slots are usually covered by a plastic
insert that reduce s the noise of the air due to the velocity of the vehicle
and they set up a venturi (sucking) effect to draw water out of the trough.
When the weep holes get clogged, rain goes down the outside of the slide window
and seeps into the trough and then pours into the vehicle.
