I have a 2006 H3. Where are the drain plugs located?

 

Each of the 4 corners of the sunroof track have a drain hole. You can only get at the front 2 easily. The associated drain tubes travel down into the quarter panel areas.

I assume your's have clogged up too.

Unknown to me, my wife complained about it at our local gas station/car wash. She said they blew the front 2 open with an air hose. I have yet to figure out if they actually cleared the dirt out that way or just split open the drain tubes.

Anyone have any ideas on how to properly fix clogged drain lines?
