Burned out cooling fan. Possible short in wire?

Hey folks. I'm continuing my quest to stomp out electrical problems
from my 944.
(1990 944 S2)

So here's the deal: Driver's side fan is working fine (it comes on as
soon as the car is started, but that's another issue). The other fan
does not come on at all (not for cooling, A/C, etc). It didn't take me
long to find out why. Upon crawling under the car, I saw that the
rubber boot surrounding the connector for the second fan as well as the
white plastic connector were partially melted.

Diagnostics with a voltimeter revealed that the second fan is burned
out (no circuit completed). The cable that connects to the second fan
tested fine (.502 reading versus .540 for the driver's side lead). The
cable looks like a$$, but it's still passing current. So I guess the
fuse for the second fan is good as well, right?

Naturally I'm going to have to replace that fan. Do I need to replace
the wire too? Any idea what would cause the fan to short out like that?
