No more AC/Defrost blower fan action

I own a 1997 Bonneville SE; and my fan blower quit. I checked the inside fuses; and they're OK. However, none of them mention the blower fan. I saw the fuses under the hood; but was unable to get any out to check them.
When I turn the dial to Max AC, I can hear the compessor; and my Father verified that it was working. All of the baffles are working. Looking at the blower, we could not see any connections that could be checked with a voltmeter.
Is there a circuit-breaker, or fuse for the Fan Motor?

Did the fan quit all at once or did it go gradually. If it went gradually replace the blower motor resistor located next to the fan. If it went all at once then you will need to replace the fan itself.
