90 Accord blower motor question
The blower motor on my 90 Accord just went at the perfect time --
snowstorm, not predicted to get above freezing until at least mid-month. I got in yesterday and noticed that 'whiff of ozone' smell characteristic of a failing motor, and sure enough, the air stopped coming shortly thereafter. At least when the car is moving fast enough the flow-through gets some warm air out the vents. I've just started looking at replacement parts, and it seems like I can get either just the motor or a whole new blower assembly. Which makes more sense? What are the issues involved? |

the motor probably will not come with the fan attached. If you are
confident you can remove the blower fan without damage then just get the motor. These things usually come off easily with a little wd-40 and patience. For the quickest replacment get the entire assembly and swap.

Are you quite sure it's the motor and not the motor speed reducing resistor? That's in the air plenum behind the glove compartment. Might be wise to check that before ripping the world apart. |

I got a lot of opinions/stories that indicated my symptoms were consistent with the motor going. I'll look into this resistor. |

If it is the motor, it may have overloaded and burnt out the resistor, which is just a few coils of resistance wire mounted on a plastic block that sticks into the airstream in the plenum. |

I'll look into this > resistor. If I remember correctly, you will find two pin connector right at the bottom of the motor to supply power to. If I remember correctly, the motor has brushes you could snap on snap off. If not then you could always try to clean the communtator. They can gum up in the winter climates. |

The highest level of airflow goes from 12V through the motor directly to ground, no resistors involved. Even if all of them in the pack are blown, the max level will still work. |

If there's any difference between the high and low settings it isn't readily apparent. Both produce about what would usually come from the lowest setting. There's a new sound, now, too, coming from someplace hard to peg in the right half of the dash, a sort of whirring when the blower is on. Something not spinning right. I'll have to pull out the Haynes and the tools this weekend and have a look in there. |
