Vauxhall Corsa B Tailgate fuse where to find it?

Hi i have a 1998 Corsa 3 door, does anyone know where to get the fuse diagram for the fuse box. I have a problem with all the tailgate lights, checked the bulbs and they are all fine, checked the wiring and connection and everything for corrosion or loose connections or breaks in the circuit and there appears to be nothing. It has to be the fuse. Let me know please.
