The heater blower motor in my 850 started to make a lot of noise, at times. It sounds as though there is a bird chirping away in it. The noise comes and goes, sometimes it's brought on by either a turn or going over a bump or into a pothole, (and we have tons of those around here). Though it's noisy it blows fine at all speeds.
I would appreciate any advice. Thank you, Peter

Mine start to chirp when it was really cold.
I pulled it out and oiled it up and put it back in and it was fine.
You can follow Bay13 instructions on how to remove it.
The motor itself comes out of the black casing by removing the back screw.

Thanks, that sounds like the way to go. As soon as it warms up a little I will try to do what you suggested. BTW, I have looked at Bay 13 for instructions, but cant find it, probably missed it and will look again. Thanks.

your blower is heading south. in 6 months to a year it will probably crap out all together - based upon my experience with my blower.

As long as it gets me through this winter, than when it warms up I will see about replacing it, or getting it fixed. What did you do with yours?

I fixed mine for $20 2 years ago
