so my 2000 v70 has a sunroof leak coming from the headliner. It appears to be primarily on the passenger side. This JUST started and I am at a loss. I poured water down the front drain holes and both seem to be draining okay... are there rear drain tubes? is there a seal somewhere that needs to be replaced?

I am about to pull off the glass and take a closer look but before doing that I thought I would appeal to others that may be wiser than I.

As I live in Oregon and the rainy season is creeping up fast this is a fairly urgent issue.

Thanks!!!
