Cooler drain on 2008 SAN 230 blocked

[shag]

Anyone know where the drain for the cooler (behind the drivers seat) drains though? I have tried stiff wire, water pressure and such but it is still clogged and pools water in the cooler cut out... :/

I know this is an old post, but wanted to give it a bump to see if anyone knows where the drain empties out to.
I currently have the same issue with my drain clogged and pooling up, without being able to get freed up.
