Electric Diagram of the Hunday Santamo ..

Greetings to all in the forum.
To my comment, I have a santamo santamo year 2001 ... and right now, the temperature is raised, the radiator fan does not start ,,, try it directly and if it works ... it tells me that it can be a fuse or a relay ,, the problem that I do not understand much of these terms ,,, respectfully requested an orientation or a manual ...
