The location of the cooling fan relay on a Vauxhall Corsa is under the dash. It is in the relay box on the driver's side.
I have the same model. It is behind the right hand headlamp as you face the engine.
Fuse box under the bonnet.
Pull it out, and plug a new one in.
It's not a relay, it's a module, located between the fuse/relay box and the inner wing. Remove the ECU, 2 x 10mm nuts, and all the wiring and fuse/relay panel from the fusebox. Remove the fusebox, and the module is clipped to it.
