2000 Renault Scenic irritating "door open" dashboard light.

I have recently acquired this kinda sickly green/yellow car and, although it appears to drive just fine, the "open door" warning light on the dashboard won' go out. I've tried slamming all the doors (repeatedly) but to no avail. It doesn't seem worthwhile to drag it down to an authorised dealer so I'm hoping there's an easy fix.... I was thinking maybe if I found the fuse, took it out for a moment and then stuck it back int... waddya think?
thanks
