I agree to not oiling until noise is located, but oiling once a year

I never thought of oiling anything on my furnace. *That's just not in
any maintenance schedule for it. *In fact it has no maintenance

Mine is 15 years old with no powered vents, and the OP never said he
had them either, or I missed that.
Mine had a squeak about the time I had a HVAC guy in to replace the
motherboard, about 5 years ago. *Squeaked for some seconds near
starting and stopping. *Wasn't "horrible," *but wasn't good either.
Might have been a squeal instead of a squeak. *Definitely not a chirp.
The HVAC guy fixed it in about 10 seconds, with a wrench. *I forgot
what he said. *Think there's a squirrel cage adjustment.
I'm not going to even look at it because mine is probably completely
different that the OP's, and the OP didn't give enough info to work
with.
But I never had a furnace that required oiling any part of it.
He's more likely to screw something up by squirting oil than to help
anything unless he knows exactly what he's doing.

Ahh...a possible case of "Just because you never had one doesn't mean
that they don't exist." ;-)

My previous furnace, a 1950's era Perfection, had a spring loaded cap
on each side of the blower motor.. The instructions suggested the use
of a few drops of oil in each hole once a year.
