Is there a diagnostic procedure for determining why the interior fan stops working?

Right after my very first bimmerfest brake job, the interior fan stopped working altogether. I was told in that brake DIY to check over here regarding the cause (http://www.bimmerfest.com/forums/sho...=1#post3124559).

After reading this post, I see the fan motor problem could be the porcupine FSU or it could be the fuses apparently hidden deeply behind the glovebox.

I'll definitely check the glovebox fuses; but, before I go out and get a FSU, may I ask if there is a diagnostic procedure for determining why a fan suddenly stops working?

Or, is replacing the fuses and FSU the only diagnostic that is available?
