Hi Rod.
A few more photo's here for you, which may help with your concern of removing fan off the top of the radiator and the rubber mounts.
Stick with what Simon as to say about the fan and it's wiring and you can not go far wrong, try at all costs not to go down the road Matt went as that is not the right way.
Once you have the fan of with the cowling you will find three torx screws holding the fan motor to the cowling these will need to be removed so you can open the lid off the motor it's self to gauge the condition of the brushes an commutator.
Sometimes the connector clips to the slam panel are hard to remove due to the torx fixing being soft alloy, this make no difference the slam panel can still be lifted free from the rubber bung.

Remove two 8mm bolts from the fan cowling centre either side, and the two clips at the bottom from the earlier photo above.
Bolts removed and cowling nibbled away round the AC joints unplug the fan loom from the main loom in the wheel arch

Lift the right hand side of the cowling from the radiator support post by lift the bottom of the fan out and the top up and off the post.

Do the same the left side taking care that you do not disturb the A/C joint

The fan should now be free and off the car so you can investigate the wiring behind and the brushes etc.
