On my 2003 Nissan Maxima SE the fan stopped operating. I believe it must be
a fuse because it doesn't work with any function (heat, defrost, A/C). I
checked the fuse box under the hood and the one under the dash by the
driver. Anyone have any ideas where else to look???

The fan(s) are probably out. Put 12 volts across their connections to
see if the come on. If not, replace them. I did. Got replacements
at Pep Boys. They still work great after a year.

Polarity?
If wrong the battery, computer, relays and other components are at risk.
I suggest using a multimeter or circuit continuity tester.
If a 12 V. potential is applied to the fan terminals be sure to have
first disconnected the fan from the rest of the car's electrics.
Also, 50% of all electrical and electronic failures are caused by open
or corroded contacts (source: Norden Bomb Sight Co., WWII).

Mike did you get the fan problem solved?

Normally, there's the resistor fan problem, but the symptom is that
the fan only works at the highest setting. Yours doesn't. Still, I
would check the fan resistor just in case. It's normally located near
the fan itself under the glovebox.
