How do you clear drain pipes in a Renault Megane sunroof?

To clear the drain pipes in a Renault Megane sunroof, first, locate the drain outlets, typically found near the corners of the sunroof. Use a flexible wire or a pipe cleaner to gently push through the drain tubes to dislodge any blockages. You can also pour a small amount of water down the drains to ensure they flow freely. If necessary, repeat the process or consult a professional if the blockage persists.
