Heater Fan wont switch on.

[gr43m3]

I'm looking for a wiring diagram and/or some pointers, on why the heater fan does not switch on, at any speed. When its switched on, the A/C light does not illuminate either.
Any ideas or any wiring diagrams, so I can somehow trace it?
It looks like the fan has 12V on one of the pins and the fan spins up, when powerwed by 12v.

I need to know model and year before I can assist....or at least which version/series...example of diagram is for 2001 model or GU2 series.

Thanks for your help. It ended up being the relay before the fuse.
