Renault Scenic 2004 and the reversing lamp and rear wiper not working can anyone tell you if this is a fuse problem and if so which fuse?

Yes, the reversing lamp and rear wiper not functioning on a 2004 Renault Scenic could be due to a blown fuse. You should check the fuse box for the specific fuses related to the rear wiper and reversing lamp; typically, these are located in the cabin or engine compartment fuse boxes. Refer to the owner’s manual for the exact fuse numbers and locations. If the fuses are intact, further electrical diagnosis may be needed.
