Thermo Fan Problems

[mrwinky]

I have a AU series 1 forte 4L, whose thermo fans aren’t running, I've tested the fans and they both work, I've tested the relays and they all work, all 3 of them, the fuses are ok, I tricked the computer into thinking it was running very hot (took sensor off back of the motor and placed cable across joints and nothing happened other than gauge reaching hot and warning sound going off, all the wires and that look ok, and neutral works fine on the 4 pin connector. But I get no volts from the others going to neutral. If I short over all the relays with a piece of wire only 1 fan works the one closest to the relays, drivers side, the other fan doesn’t come on, I'm guessing there is some sort of switch controlling the path somewhere else but don’t know where, is there a wiring diagram around for this? I check the wiring diagrams on the site but couldn’t see it there any ideas?

Any help much appreciated.
