Sorry for the delay in replying - I have been busy with some other things. I did some more testing tonight per Arthur's suggestions and when I disconnect the pigtail, the fans turn off. Tonight, after driving around town for a while with the A/C on, the fan ran for at least 30 minutes after turning the A/C off. I let the car run for a while, I left it with key on, I turned it off and then turned key on after a minutes - and the fans kept running (they didn't run while the car was off).
I'm beginning to think this is connected to my other electrical issues - see the following thread:

I have been monitoring the voltage put out while driving, idling, etc for a few days now - after having replaced my voltage regulator. It's a little better, but not above 14 volts - except maybe on a cool day with all accessories turned off. My central locks still do not work, and the convenience system works sporadically.
Any help would be appreciated.
