I replaced my blower motor with a NAPA #6551005. Works perfectly, and wasn't too expensive (around $60). The former fan rusted to bits from the inside out and squealed like something awful. Installation was a snap, no reversing any wires. No fittment problems. The only thing I did was scuff up the paint on the body of the new fan a bit to promote better grounding (on both the part that mates with the housing, and the 3-prong ground thing). -Luke 10270
