IIRC, that's the coolant level sensor. Not related to fans not working.

Check the fusebox under the hood for a cooling fan relay. Swap it for another relay that has the same part number and see if your fans work. If they do, put the relays back in their original places and buy a new relay for the cooling fans.

Additionally(to checking the relay), find the electrical connection for the fans, unplug them, look for corrosion and is needed, clean them, plug then back in.
If the fans have their own sensor to turn them on, check that connection as well.
