The leak on my window turned out to be the seal around the bottom half of the window,,(I think its called the wiper seal) was about 1/4 inch gap against the upper sill. I called Herr and he sent me literally 9 feet of seal. I cut the new one installed it and not a drop has made it through..While waiting for the seal to arrived stuffed a plastic sandwich bag or part of one and covered it with silicone. That also stopped the leak.. I have been through some heavy rain, snow and ice with no problems.. good luck with yours
