Ok. so the fan works when directly connected to battery

connecting the wires together at the fan switch doesn't make the fan start??

is power going to the rad fan switch?? use a multimater againste the body or back to -ve battery terminal to test for voltage

Fuse is good with good connection to the fuse socket??

I'm not sure if there is a relay just for the fan, power will either be picked up from the ignition, so comes live with everything else or a permanent live (my espace is permanent live so in hot weather I turn off the engine, lock up and walk away and the fans will continue to cool the engine, it was wired like that in the factory!)

have you tested continuity of the wire?? (is it broken) again with the multi meter, set it too ohms (little horse shoe .lol) and the diode sign touching the 2 testers together should give you a beep!! you can then test each wire from end to end for continuity if there's no power to the rad switch i'd start with that and trace it too the fuse

sorry if this seems a little obvious but i watched a fully qualified electrician spen 3 hours on a lighting circuit before i pointed out the bulb had blown! lol unfortunately for him i got to the pub 1st that evening LOL

Relays are normally with the fuses, but others are dotted in groups around the engine bay. again use the tester set to continuity to see if the they are connected to the fan switch

sorry i can't help more than this. i'd have a good look around with the multimeter to rule out broken wires and weak connections. As a last resort i'd run a new feed from the battery (with an inline fuse!!!!) to the fan switch and disconnect the original feed, creating a new circuit! it may seem amatureish but with a propper fuse and zip ties to run the cable along the existing loom it's gonna be ok and better than loosing the engine!

good luck
