Sounds like bearing or brush noise. I don't think it's the fan
whacking against anything.
I've found one other mention of this when I did a web search.
Anybody else had this problem?
I'm thinking of removing the blower motor - it looks like
I should be able to take the ductwork apart under the passenger side
dash
and get it out pretty easily. Am I nuts? Is it not as easy as it
looks?
Am I going to end up tearing half the truck apart (glove box, dash,
etc)?
Once I get it out, I was going to try oiling the shaft bearings and put
it back in. Am I wasting my time? Do I have to just replace the
&*$(*&# motor?
Thanks,
Max

I scoured around the parts stores near here, and
couldn't find anybody who stocked a replacement blower motor
for this truck. I could order one for $70, and wait 4-5 days, or just
pay the big money at the local GM dealer, and grab it.
I opted to pay the money (about $100).
The motor comes with the drum fan blade already installed on it.
You have to lay down under the dash, unhook the rubber
shroud from a plastic hook on its bottom, and then man-handle
it to get it out of the way of the motor.
This latter part is darn near impossible without destroying the shroud.
I opted to just surgically cut the shroud away with a utility knife.
That way I could make a clean cut and remove it in one piece,
leaving the top half in place. Also, you want to unplug the 2 wires
going to the motor before you do this.
Next, you'll need a small nutdriver. A small (1/4") socket drive
with nut driver attachments is even better. The motor unbolts
with 5 small hex-head screws. These are a pain to get
to, so be patient. Then the motor pulls right out.
The new one drops right in (seeing as how I bought an original GM
replacement ;-) ).
There was nothing "stuck" in there. No leaves, insulation, or other
offending material. The motor bearings were just getting noisy, plain
and simple.
I shoved the shroud piece back up into place, and held it basically with
1 sheet-metal screw and duct tape (makeshift-style!). Don't sweat it.
None of this will show at all if you are careful.
Hook up the wires.
Voila! No more noises. The fan runs as quiet as can be.
I hate to spend a hundred bucks on a repair like this, but the
ease of repair and drop in my irritation level are well worth it!

So far, although this truck runs really nice, there have been a handful
of
these very annoying things wrong with it, which already makes me
trust it less than I trusted my previous 1989 Chevy K1500. I've had:
- a weird skinned wire under the drivers seat that kept blowing the fuse
that
controlled the lumbar support, electric door locks, and cigar lighter
- very annoying rattle in the center console between the front seats,
which I
solved by removing the entire console top, and lining the whole thing
with
a thin sheet of felt (why don't they do things like this at the factory-
... any idiot
can see that two large plastic pieces, just snapped together as the
console,
are DOOMED to rattle!)
- the dreaded wipers that work, then won't work, then work... which I
seem to
have fixed by removing the wiper motor cover and reseating the connector
and circuit board... it's been months since it's acted up, so I don't
think I have
the faulty solder-joint thing... but if I do, at least I know how to fix
that one)
- this noisy blower fan
- and now, finally, I think I'm starting to hear a bit of "ticking"
noise coming from the
speedometer when I first take the truck out in the morning, between 20
and 40 mph...
I assume these are all electronic (I don't think they've used a
mechanical speedo
cable from the tranny in years!), so the noise has to be coming right
from the
speedo itself
