On mine, the window leaked from the top. So I just filled the space between the top of the window and the side of the coach with silicone. I also put it down the front side of the window so water would not leak in there if you were in a rainstorm while driving. You can’t see it and it stopped the leak. Unfortunate, I did not find any way to fix the “dimples” except to sell it. Someone told me that they thought the water the glue or something inside the wall that the water dissolved and formed small hard nodules. Actually my wife solved the issue by sewing a three pocket rectangular panel the size of the space where the dimples appeared and putting it up with plastic hooks. It gives you three blue jean pockets to store stuff in. I liked it so much we moved them to our new Axis, even though we did not have that issue.
