as the title says, is there i way that i can do this myself? i got a couple leaks up at the top that i just found out about the other day. is it as simple as pulling the trim around it and maybe throwing some kind of silicone/sealer in there, or does the whole thing need to come out?
Depends how correct you want it. I'd pull the trim, cut it out, reseal and install. Most glass shops wont guarantee it wont break if they pull it. However they have a better chance of NOT breaking it than most people. If you aren't looking for a long term fix pull the trim and load it up with silicone. Clean it up with something first.
