Unfortunately there are no pictures in the part that explains cleaning out the weep holes. If I remember correctly there were no weeping hole covers. I used a thin twist tie to clean them out on mine. Once cleaned out you can see the water flow out from between the window and down the side of the RV. Good luck.
