If it's got a green wire on one end and a white/brown wire on the other,
that is indeed what it is.  The bearings in the fan motors have a nasty
habit of periodically binding up (not quite siezing) causing the motors to
draw excessive current.  When (not if) this happens, the circuit breaker
starts cycling off and on, which is much preferred to having a fuse
repeatedly blow.

Also correct.  It shows up as a regular old fuse on the wiring diagrams.
The fuse was snipped out and a circuit breaker was installed in its place.

Really?  True, you're not likely going to find an exact replacement, but
most any auto parts store carries a suitable 25-30 amp replacement.  The
original fuse was rated at 35A, so you should be safe with a 30A circuit
breaker.  I know the Advance Auto even in this jerkwater burg has them.
Tiny aluminum box with spade connectors, costs less than $2.50.
