Absolutely!!!!! If its coming out under the car they are working.

However I had a thought the other night when I was lying awake thinking of other things (and trying to get my mind off them - no, nothing exciting!).

Do you run your A/C, is it possible one of your A/C drain hoses is leaking?

I recently had one of mine replaced as my mech said is was in a pretty perished state and if I had ignored it I would wind up with the system dumping the condensate into the footwell, from there it could travel back to the rear. Second idea - somehow it is dumping condensate into the vent where it is flowing down the vent and coming out under the front seat (you know the vents for the rear cabin).

I would still be trying the simple methods of identifying the leak point with a hose and 2 people before launching into dismantling things.

It may be your rear window seal - spray the crap out of it with the hose and see.

Cheers
