Cooling Fan help

Hi,

Was out for a run today in my MX5 and discovered that my radiator fan is not coming on, when I came home I tested the fan itself and it is working. Where is the relay located or anyone have some idea as to why the fan is not coming on?

The Gleneagles is a 1.8 - the cooling fan is run from the ECU rather than through a thermo switch as with the 1.6. The ecu does rely on readings from the temperature sensor mounted below the coil pack at the rear of the engine to start the fan though so a problem with the temp sensor is a possibility.

Apart from that the relay is in the main fuse box, under the bonnet on the drivers side  IIRC its an LA10. There are several on the car so easy to swap over to test.    

Thank you for your help. Started the car tonight and while she was heating up I took the relay out and put it back in again. Then when the car heated the fan came on! I hope it was just a bad connection.
