2019 Heater / Defroster fan buzz?

Hello Gang,

Yesterday the defrost/ heater blower on my 2019 developed an odd buzz, it sounds like a playing card in bicycle spokes.

I'm on my mobile phone and couldn't locate the site search, sorry.

Has anyone come across this issue before?

 

When was the filter last changed?

And you can drop the blower and see if something like a leaf may have worked it's way in.

Always start simple!

 

Check for varmints in the filter/fan box.

 

That would not be completely out if the question, we recently had a ground squirrel get caught in the serpentine belt of my daughter's car. That was a mess.

I guess I'll start with the easy stuff first.

 

Your filters probably clogged, causing it to sag/tear and contact the blower wheel. Also mice.
