Cooling fans

[JamesSim]

Hi Folks,
My cooling fans are not operating, the last time this happened 2 years ago, I just cleaned the connector blocks at the fan motors and a squirt with WD40 and all was well, that was my first port of call this time but to no avail.
I checked the fuse and found this to be blown, replaced it but nothing again took the car out around the block but it overheated, the fuse is still intact, the fan blades run freely by hand.
Is there any other things I could check?

Many thanks.

I would try the relay for the fans, it’s under the steering wheel with the other relays and fuses, usually yellow in colour.

Thanks Stuart.

Hi Folks,
It's not the relay, got this checked today and it's ok, could it be a sensor or are the fans a bit susceptible?

Kind regards,

James.

One check you could try is disconnecting the temperature sensor, this Is the rearward one of the two. This will then give a fault to the ECU and set the temperature to 95 Deg.C which should put both fans on. Although you have had the relay checked (they're are two BTW one for each fan), I had one fail and although it would energise the contacts were U/S, you could also swap the relays around to check.

Try the connection plug at the fans

Sometimes look like this after a good cooking

Thanks Nick,
I'll give that a try tomorrow.

Hi Graham,
Thanks for that, that's what I checked first, as I had issues there before I had them disconnected and cleaned etc.

Changed the 2nd relay but that didn't work, fans wouldn't come on, noticed a small fine jet of water coming from the area of the fan switch, hopefully that's all it is.
