Cooling Fan

[Matt]

I have a 1.2 1999 v reg fiat bravo, I can't figure out why the fan will not come on to cool the car down. I have looked on this forum on the Fiat forum but from the few answers I have read I haven't been able to find the reason why! I have changed the red relay just in front of the battery, I have also (today!) changed the fan for a second hand one from a breakers yard. Is it the temprature sensor? or some other sensor I need to poke or change? Shall I just bite the bullit and take it back to the garage and get them to figure it out?

There is no switch or anything on the side of the fan, it's controled by the ecu.

Any help would be great! Thank you very much!

If it was the temp sensor that was duff mostly likely wouldn't get a temp reading at all (like when you disconnect it the temp needle does not move at all)

More likely to be the fan switch itself not sure where this is located on the 1.2 radiator\fan someone on here will know though...

So after much fudging around, almost installing a whole new switch going to the battery and routing it somewhere through the car, it turned out that the fan was fine, the relay i replaced was fine. All it was, was the wire coming directly out of the fan connector had corroded away! A quick snip and rewire, all is now fine with the world, fan works and car doesnt overheat! Hurrah! Now to get the see how much it costs to get me gearbox reconditioned, install a new clutch probably and make the rear lock work! Not much then!
