98 Civic Blower motor noise

[Question Quigley]

My '98 civic will be humming along with the blower fan on and all of a
sudden it will make a gawd-awful noise like something is stuck in the fan.
I pulled the fan and operated it out of its housing and it seemed to be OK,
with no noise and no noticeable wobbling or imbalance.

Any ideas?

Thanks,
Dennis

I had a similar problem with my Accord. Turned out to be from squirrels
nesting and eating in places where debris could fall into the cabin air
intake. At least that's what I postulated since the fan housing where
the impeller is was full of leaves, half eaten acorns, twigs, and such.
I've had to remove nests from the Accord and my truck on many occasions
even after they'd only been sitting overnight. Industrial rats. The dogs
got the last one.

Thanks, Nasty.

I pulled the fan and cleaned it out, but I am still getting the noise after
a few minutes. I also disconnected the resistor which let the fan run on
high only. It was quiet for a few minutes, but the noise came back. The
inside of the housing appears clean (no debris) so I'm guessing it is the
fan motor itself.

Again, thanks.

Didn't mean to imply that you overlooked debris in the blades. Just
kinda a general comment. I guess it's not out of the question that the
damn think is just worn out eh?

If you've addressed interference and debris, the motor bearings are the
next suspect.

Is there ANY play AT ALL in the shaft when you wiggle it? If so, that's the
problem. Also check that the blower fan itself isn't loose on the shaft.

Luckily, blower motors are a dime-a-dozen in the wrecking yard.

Well, I'd like to get to a junk yard, but there is nothing really near me.
So I ordered a new one for $37 (including shipping) on ebay.
