90 Accord blower motor question

Discussion in 'Accord' started by Pete from Boston, Mar 2, 2005.

  1. 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.

  6. Nope, not at all. I got a lot of opinions/stories that indicated my
    symptoms were consistent with the motor going. I'll look into this resistor.

    Might be wise. 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.

    which would likely have the same smell.

  12. 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.

  16. On the contrary, I do get some airflow at a very low rate. 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.

    You might accomplish a cheap fix by disassembling the motor and
    lubing its bearings.

    Can you get the motor out without removing the evaporator?
