C70 - electrical adjustable drivers seat not working

[M400 NBL]

Does anyone know if there is a fuse or something simple that might stop an electric seat on a C70 from working. Wouldn't normally be a problem but I am going on holiday without the missus and she may want to use it....except she won't reach the pedals with the drivers seat in it's current position. I'm assuming that there are 2 motor and so unless both have packed up it my be the supply to the motors?

I will have a look myself later but I thought i'd ask some of the experts first!

Thanks in advance
