Assuming it is a manual roof. Lift out the glass by raising it at the handle then pushing in the little red tab holding the round metal rod in place, pullthe rod out, still attached to the roof. Lift the roof to the vertical and lift it out. Reassembly is the same etc.
You will see two very small holes in the front corners of the plastic wells at each side of the roof.
Use a piece of welding wire to roddle it. It may work or you may have the clio curse.
