After doing some searching around about how to solve the wet floor behind the driver's seat in my new (used) 2005 S40, most of the advice points to checking to see if the sunroof drain hose is disconnected or clogged. Is that something I can do, or will it need to go to the dealership? I just got the car yesterday, and the weather has been sunny and dry, but the carpet and mats are dripping wet behind the driver's seat. I'm supposed to get it inspected tomorrow, then sign the final papers at the used car store. Help!

 

A good way to check the drains is to get someone with a air hose to blow compressed air down the drain holes. You should be able to hear the leak inside of the passenger cabin.
