Right been down the garage and sadly it's the 3 speed fan variant in mine so the resistors not an option.

So rather than drag things out and for peace of mind I think I'll bite the bullet and contact Jules for the new 2 speed fan motor and resistor.

Thanks for all the info everyone. You've still prob saved me £200 with the links provided than had I just let the garage sorce one from their suppliers.

Cheers
