On USA model E53 with the 3.0 engine the BIG 50 Amps fuse for the Aux fan is located in the fuse panel in the glove box. An easy way to test to see if you have a blown fuse isa to remove the connector from the fan and with a volt meter set to volts one of the big lead will be 12 volts and the other big lead will be the ground. Insert the probes into those two terminal and you should see 12 volts.
