How can I fix my Citroen C5 2002 REG?

Either the back window is leaking or the trunk lid seal is leaking.Check for trunk lid adjustment on hinges of lid.Also check real good around the window seal at the bottom. There should be a rubber plug in a drain hole in the bottom of trunk,remove rubber plug.If no hole drill one in the lowest area, check under that area of the car to be sure not to drill anything else.You should be able to tell once youve drilled through trunk deck.
