The rad fuse in the fusebox has melted and obviously the fans aren't coming on at all and the cossies overheating. I tried stripping the blue and brown wires and insulation taping them together however it still doesn't come on. My mate reckons I need a new fan switch anyone else agree??. BTW I know the wiring on cossies is Sh*t and will be getting it all re-wired.

Cheers

Such a problem that ford mentions it in the old motorsport prep book. Get a replacement fuse box off jacko above and then replace you fans with a pair of spal or similar slimline fans as they draw bugger all current compared to the weighty ford originals.

i only know cos it happened to a mate concourse car it cos they dont get used much and the fans seize

They used to melt the fuse boxes when nearly new.....mine did it and the original fans were perfect condition. Think its just a case of over the years the wiring has degraded a little as well as every thing else so its led to the demise of an already over stress circuit....except in your mates case where it just seized completly lol

If you wire the starter solenoid feed to the fans circuit with a diode they will get exercised everytime you start the car, and so won't seize.

my mate is a car trader and back when 3dr cosworths were new he brought loads of them to sell and did very well from it the best thing he did well in was salvaging car and a lot of the time it was fire damage the fuse box had gone up so when i started building my 3dr he reminded me of this . well i had to get a full loom for my 3dr build and guess what the fuse for the fan was melted in the box so i had a chat to RYAN at car looms and i think off the top of my head it was £70 but RYAN made me a loom that is on its own it has its own relay x2 its own fuse x2 and bolt straight on to the battery and on to the fanse indervcholy so if one stops working yes the fuse will pop but the other fan will still run wich in my eyes is a good thing . when i go out into the garage today i will take a photo of the loom as its not on the car yet as the car has no motor in it yet.

Cheers for the replies boys. Jacko with regards to the above although the wires in the fusebox aren't burnt the fan fuse is still connected to one of the wires and when I complete the circuit the fans come on again, so aren't seized. No doubt the overall wiring needs to be changed but if I just strip the wires and solder in some fuse holders and replace the fuse will this allow the fans to start working again when I drive it as a temporary solution?

if you think its the fan switch just bridge the connectors they should then start up.

In the future, use std fans and this:
