X5 with no heater blower

[Speed addicted]

My wife is currently driving my 2001 X5 (I'm offshore) and the heater fan has just stopped working. Her dad has had a look at the fuses in the glovebox and boot with nothing obviously wrong.
Could this be the hedgehog thing or is there something else I can tell them to look for? The car is driving and behaving normally otherwise, and there have been no problems previously.

Cheers folks, I've told my wife to pull the relevant fuses while the ignition is on, hopefully that'll fix it long enough for her to get home.

Is there any way to tell what's wrong between the hedgehog or the motor without replacing them?
Any ideas how much a hedgehog (really should find out what that's called, I'll look silly in BMW parts!) would cost?

Sods law means that I'll be replacing whatever is still working first.

Thanks for the replies, pulling the fuses hasn't worked. I'll get it sorted out when I get off the rig (and when I have to drive it!).
