My blower motor finally quit after 7 years. I got my replacement motor from a junkyard for $35 (dealership charges $98 for a new one). The installion was a pain and took me most of an afternoon. The motor is under the passenger side of the dash and is a difficult fit and hard to reach a couple of the screws on the mount. It works now and I don't have any weird noises either. Since it's very difficult to reach the back the technician may have put it in slightly crooked and not cared or just not put the back screw in, which could make the blower wheel rub on the duct. Some of the motors come with a foam gasket (like my '97) and some don't (the motor I got from an '01). Some of that foam gasket may have torn on installation or has come loose and is rubbing on the blower wheel (it looks like a hamster wheel).
I also found out that the '97-'03 all use the same blower motor. The casing may look a little different, but they all fit (a little tidbit I found out from my local Ford parts guy).
