Well now I have a new cause for Nissan motor blower noise.
I ordered a new blower motor and it came in this week. My son came to visit so we could replace the blower motor. I let him take out the motor so he would get the experience.
Turns out there was a peach pit inside the squirrel cage fan. Yes, a peach pit.
He's had the car for years (purchased used) and said it has always made that noise. I assumed it was a bad bearing.
So this leave only a couple possibilities.
1) Was put in there at the factory ... 2) Practical joke by someone who previously owned the car, or someone played a joke on the previousl owner.I've looked all all the vents and so forth and it seems impossible for the peach pit to have fallen in from the dash or an air vent.
We took the unsued, but new motor back, and the store issued a full credit.
