I was under the impression that the blower was initiated in the 1999 years, but perhaps it is 2001? The program compares the evaporator temp with the outside temp and can run the blower for up to 10 minutes until the temps equal. That will effectively dry off the evaporator.
My wife's car does that some times and I don't know what it is. Almost sounds like a water pump circulating to cool off the block, but that can't possibly be it. Another possibility is the evap system pushing fumes to the charcoal cannister?
