e53 x5 aux fan fire

[rustyghia]

hi all, i've just had a fire in my 2003 e53 in the aux fan, i've replaced the fan and it still doesn't work, the fuse's are all fine, but there's no live to the fan, so the relay is obviously shot? but i can't find the aux fan relay ? i've contacted bmw but they are no help and i've searched the web to find the location but still no joy, i've found the relay box under the screen but i don't know which one it is, thanks for looking, dean.
