2002 V70 Rear Sunroof Drains?

[krenekj]

After the first heavy rain of the season, the Black Widow suffered catastrophic water penetration on the passenger floors (front and rear) due to a plugged front sunroof drain. Both fronts are now clear and the interior is drying out.

I want to verify the rears are clear - how do I get to them? Do I need to remove sunroof glass to see them and get my compressor in there to give it a quick blast of air. Or is there an easier way? I'm not looking to see the tubes through the pillars, but just blow some air through the lines.

Thanks.
