1968 Heater fan motor
I am replacing my heater fan blower and noticed that the replacement I bought from NAPA did not seem to blow as much. After checking rotation and making sure it was clockwise, I used a Tach to measure shaft speed. The new motor spins at 1/2 the rpm as the old one at a full 12 volts. I returned the fan to exchange for another brand that NAPA sells and that too, was 1/2 the RPMs of my old noisy unit.
Does anyone know why there is a difference? Where can I get a motor like my original?

Is that a multi-winding motor for speed selection? Meaning 3 terminal connections. I don't think they used resistor banks to control fan speed back in the day? Anyway, it may be the motor was getting power supplied to the wrong low/med connector?

Ah, one wire. Well you're electrically literate and that's in your favor. Surprised the after-market was so far off unless it's a "universal" motor for several applications? Unfortunately, none of them yours.
