Another question: just how freely should the motor spin unaided when given a manual flick with the hand? Without knowing this it's difficult to assess if my WD40 has been applied liberally enough and in all the right places, and to gauge whether there's anything further amiss with the motor.
Currently, when I flick the white plastic blower blades with my hand, the motor spins on its own for about 1.5-2 revolutions (I'm guessing). It comes to a stop pretty quickly after this and it feels like there's definitely quite a bit of friction within the whole assembly i.e. the spindle isn't constantly loosely turning in response to any movement of the unit (e.g. when picked up)
That's about the same as mine. Before WD40, no free spin at all after a flick; after, about 1 rev. Bear in mind that electric motors spin within magnets and so never spin completely freely like a bike wheel. Mine is now back in car and, after fixing resistor with 215 degree thermal fuse from ebay, working fine so far. I expect trouble down the line however - WD40 never a permanent solution - and will prob replace motor next time.
