You can check behind the glove box. You have to remove the glove box to access it. Use the owner's manual to know how to find it.
To remove the dash in 04 Renault Megane Grand scenic you need a tool box. The tools in the tool box will help you open and then remove the dashboard in the 04 Renault Megane Grand scenic.
Linked to the radio fuse 15amp in glove box of megane 05. Just changed fuse and everything is now working fine.
It's in the passenger footwell top left hand side below the glove box
Change the fuse in the box next to the glove compartment.
There is one in glove compatment's roof that drops down and one under cover by battery in engine compartment.

Listed in your owners manual and on the vehicle somewhere. Look on the drivers door post, truck, glove box, console, etc. It is there somewhere.
Remove the glove compartment of the car by simply downloading strip that is above it and cover the right side button for a passenger airbag deactivated. After removing the glove box, at the bottom of the center console is triangular lid locked with two screws that are uncovered with torx 20. Remove the cover and the filter is located behind it.
