Water Leak

[jbroker730]

My 2003 GX 470 rear floor carpets are wet. I had it back to the dealer, who couldn't find anything. I was told it may be clogged sunroof drains? How do I locate and clean them?

Any ideas? The smell in the car is horrible.

How much does the dealer charge to clean them? I believe they might be right, I've heard of this problem before but so far not in the GX yet..
