Citroën Xsara SX: Front windscreen wipers inoperational?

There could be more than one fuse panel. The motor would probably have its own fuse.

One somewhere on the driver's side, one in the engine compartment, and one possibly on the passenger side?

Do you have a library around that might have a manual on the shelf? Have you asked at any parts stores, like Halford's?

Damn French rubbish - I have 37 year old German Opels on their original wiper motors, never had a problem. Anyway, you have no spare fuses, but you CAN remove each one and check it hasn't blown. If it has, remove another of the same rating from another slot, use it to replace the blown one, (note down on paper what you are taking from where) and try your wipers - if it blows again immediately, then you know you have a problem with the switch/wiring/motor on the wiper circuit.

My local pound shops sell 30 fuses for 1 pound, you should never be without them. Removing a motor is all well and good, but are YOU capable of testing/fixing it, or have you sourced a spare?

Im guessing the motor itself is behind the dash like a lot of cars. you can go down to a parts store and ask them if they have a diagram that may show you where it is. Or go talk to a garage that works on those cars they already know and Im sure its a pain. The last one I did went to my mechanic the transmission is for the wipers should be behind the grill behind the hood there may be a grate you can look through to see if the wipers are trying to move. If you dont hear the switch turn on the motor it could be a switch you need to test it if you can

Inoperational

Have you checked your wiper motor out and the wiring to it? That is where I would start with.
