where is it? usinga voltmeter today i tested the connections over the fan switch and there doesnt appear to be a current getting through. ive checked all the fuses under the steering wheel, by the ECU and under the passengers side dash but all seem ok.

so where is the fuse for the radiator fan?

cheers

are there fuses in the block under the battery tray?

had a look.. well tried too... cant even get my arm under there let alone have a look...

anyone?

very desperate

i read in an old post that its a big fuse behind the battery.. ive just looked and its not there..

Hi,
Its at the bottom right hand corner of the fusebox under the steering wheel, inside the car(got a picture of a fan and radiator next to it)

Thanks

Hi,
The switch to put the fan on, is on the side of the rad next to the carbon can, normally shorting out the two wires with a paperclip can test if the fan is working (with ignition on)..

Thanks

yup i knwo.. ive tried that.. and it didnt start up. ive checked that fuse and its fine. i also used a volt meter to measure the current with the ignition when bridging the connector at the switch and there wasnt a current...

Put a direct live feed to the fan from the battery. Then try the shorting of the switch job again.

Cheers

will have a proper look and take the rad off etc on thurs.. havent got time at the mo luckily i wont be doin long drives till then anyway

Hi,
The loom connetor for the fan is under the expansion tank as far as I can tell(on 899cc anyway), maybe this has a bad connection..

Thanks

its all a real pain in the arse to get at though.. im gonna have a full look about on thurs as ive got the day off..

wil make sure the fan spins up first.. but whether it does or not, there isnt a current getting to it ..

I assume this is a cinq?

If so, the fuse is in the fuse box, bottom right, number 3, should be white, 25A, with a little fan symbol next to it.

to be pedantic, test the voltage first, not the current. If the fan is faulty (open circuit or high resistance) then you'll never get a current flowing, even if there is a voltage (ie. even if the rest of the circuit is ok). And there won't be a current flowing until the radiator fan switch turns on
- take the plug off the radiator fan switch (on the side of the radiator)
- on the plug (the dangly bit, not the bit fitted to the radiator), measure the voltage on each of the (2) connectors in turn (using the engine block or bodywork as an earth (-ve) connection for your voltmeter)
- if the fuse/circuit is ok then one of the connectors will show 12V (and the other nothing because it's connected to the fan motor)
- you shouldn't need the ignition on for this - the fan circuit is always connected so the engine is cooled even once it's been turned off.

If there's 12V at the radiator fan switch, then try a similar test at the fan motor connector.
