while looking into why my brake lights were staying on i pulled the back seat out and found water under the seat but no water in the foot wells.
Could this come from the sunroof? 2001 s60
Thanks

 

It is possible one of the drain tubes popped off.

 

ok i,ll look at that. Where are the drain tubes?

 

That is the bad news. They are under the headliner and rear panels by the back windows.
If you can leave the back seat out and open the sunroof. Then poor some water outside the main sunroof track. Also if you can park on a little bit of an incline. Then you should see the water drain by the back wheels. If it does not from one side then you know it must be that side.
