I don't know if this is the case with the 240 blower motor, but some motors are "universal" and will operate on either AC or DC.

From Wikipedia: "The universal motor is very similar to a DC series motor in construction, but is modified slightly to allow the motor to operate properly on AC power. This type of electric motor can operate well on AC because the current in both the field coils and the armature (and the resultant magnetic fields) will alternate (reverse polarity) synchronously with the supply. Hence the resulting mechanical force will occur in a consistent direction of rotation, independent of the direction of applied voltage, but determined by the commutator and polarity of the field coils."

So it is possible the 240 motor is compatible with that of a vacuum cleaner.

Hey,another source of parts!

1985 244 "Alfsen" (wife's car - the good one)
1984 245 "Buster" (the kid's car, now sold)
1985 245 "Cosmo" (parts car, sold off for move to WA)
1985 245 "Daisy" (back seat down, full of tools, the work truck)
1985 245 "Earl (CA vehicle 'retirement' program)

Can you tell I prefer the 1985 model 240? Better headlights than
the plastic 1986+ and nicer belt adjustments than the 1984s and earlier!
