97 Accord - ventilation fan noise

I own a 97 Accord with about 120,000 miles. About a year ago, I
started noticing noise coming through the vents from the ventilation
fan. At speed 1, it sounds as if the fan blade is catching on
something. It sounds like a fast clicking noise, turining up the fan
speed muffles this clicking noise since the sound of the air
turbulance overpowers the noise.
Has anyone had similar problems with their ventilation fan?
Is it easy to get to, to either replace or lube?
Thanks

 

I

possibly a leaf that got sucked into the system? youll never know until you
take the fan out.

I had a similar experience with my '97 Accord. But, the noise occurred when
the fan was in the second speed. I never got used to the noise, and ran the
fan either in first or third speed.

I agree that the only solution is to take the system apart and
remove whatever "the fan blade is catching on..."
If you don't know how to do it, make an appointment with
your favorite mechanic and let him or her do it--for a fee.

Hi,
Maybe something like dried leaf or small debris is stuck in the cage?
Check it out.

If you look at the vent air intake slots in the plastic plenum cover at the
bottom of the windshield you'll se that there is no screen behind them to
prevent debris from entering. You have to be meticulous about keeping that
area clean during Spring and Fall when there's lots of plant debris around.
If it's just that it will eventually clear itself - you can try turning the
fan up and down the speed range and changing the vent outlet flows, which
sometimes dislodges it.

I've also seen a mouse nest in the fan cavity - the dried up little baby
mice make a *lot* of clicking noise as well, usually with a fan which is
out of balance and vibrates at the high speed... and it's quite a big job
to get them and all the torn paper & rags stuff out of there.

If you like to mess about,try reversing the motor wires for a few
seconds. The motor could clear the leaves by its basic design of the fan
type. Its designed to scoop air, leaves etc. Reversing it could clear it .

I wouldn't get too concerned here, reversing the fan direction could be a
waste of your time, that fan is easy to remove. under the glovebox area you
will see the bottom of the motor assy. there are 3 brass 8mm bolts
eqidistant from the center of the motor that hold the fan and motor in as an
assembly, disconnect the 2pin connector and remove those three bolts(they
also can be removed with a screwdriver) then the motor/fan assy will drop
straight down this will not only allow you to clean the leaves from the fan
cage, but will also provide access to the blower box where there is probably
more debris to be cleared out. With any luck its only leaves, however I
have seen rodents deposit food, feces and thier young in there...Have fun
