I haven't solved anything yet either I don't think its possible to find that outer seal that the glass slides into. I have spent bookoo hours researching it on the net . I think a person is going to have to change not only that seal but also the felt track that the glass slides in to cure the problem completely. And as one thread suggested make sure the drain holes are open.
Still dripping in kansas
I just found out the felt track doesn't solve the problem. Windows
open smoothly, but I still get the same leaks
. I found an exact match for the felt track: CRL flex glass channel, #21116181951C, (800) 421-6144. A part of a role is available from - RV Doctor George in Sacramento, CA (916) 927-7837. My next step is to put plastic trays under windows
as suggested by Jack Maloney.
