2004 status a/c water drains on passenger floor

[michigander2u]

I took this 2004 to the dealer and they blew out the drain line, fine, now it drains into the passenger side under the seat wont drain outside like its designed to. i have water (very stinky water flies love it) under the seat and sloshes around the floor front and back, i have several times blew out the drain line but this only makes it worse..warrenty is gone but have a aftermarked and they wont cover it..
what do i have to do to get the water to drain outside not inside.
thanks

are you sure it's the AC line and not the heater core?

it is the ac causing it. the drain line going out was not properly installed, it sat in the middle of the rubber drain that drains to the ground outside, causing it to run back into the firewall inside down the passenger compartment and from there has no place to go but under the seat, borrowed a scope and there was nothing blocking the drain, just took the outside boot off and sealed the elbow with silicon so far so good..
