Leaking sliding back window

2006 back glass leaks, what can I do to fix without changing to a reg one? I have a pond in the floor well.

Be sure it's not the 3rd brake light above the back window. Fairly common leak point.

I'll check that thank you

Just had to fix the third light on my '14.

Third brake light is leaking a bit on my 08, lens itself is sun baked and cracked, guess I should replace it one of these days.

back glass is usually good, they urethane those suckers in pretty well.

I was reading a while back where someone posted about the drains were clogged and they showed a fix. Maybe do a google search and you may find it.
