Been there done that. I agree with the suggestion that you need to have your dealer look at it. You will save yourself a TON of time and frustration if you do.
After Hurricane Katrina we had to have our coach repaired. They had the bedroom slide out and when it came back to us, it was leaking. The seal wasn't tight across the top when it closed. We figured since the dealer was the one that screwed it up in the first place it wasn't going back there!! So, we spent the next 6 months trying to get it fixed. Finally got it but what a pain!!!!
If you do attempt to work on this yourself one thing to remember is that everything tends to work the OPPOSITE of what you expect. As an example, if the top of the slide is not tight when you close the slide, I would be looking at the BOTTOM of the slide to adjust the tilt of the TOP back towards the coach...LOL
Like I said...if you can at all, take it to your dealer!!!!
