Fan has stopped working going to buy a new fan switch is there anything else you could suggest:

Bridge the 2 wires together on the wiring plug, if the fan comes on when you turn the ignition on then it's the switch. If it doesn't, then it's something else!

Exactly what he ^^ says, this is the first thing to do.

If it's a Cosworth then it's likely the fuse has melted in the fusebox (Caused by Ford fitting a switch that isn't suitable), but irrelevant of this the fans should be rewired anyway, if you do a search on here you will see all the threads about it.

If its a cossie i,m fairly certain if you bridge the switch the fans would run still with no ignition?

Found the problem it was a 30 amp fuse in slot 11 of the fuse box

Classic problem, as I say above, it is common for it to melt as well!

Rewire the fans BEFORE it damages the fuse box etc, the standard setup/wiring is shocking, the fuel pump also suffers from old wiring and cause cause a meltdown, these are two chronic weak points and both need rewiring!
