Blocked blower intake?

So when I turn my heat or cooling up to the highest fan level it gives a terrible rumbling noise. It almost sounds like the intake side of the blower is blocked and creating the noise. My first impression was leaves. Only problem is I don't now how to check that? Is there a way for me to look and see if leaves or something is blocking it?

Look under you glove box, way in the corner of the passenger footwell and firewall. Thats where the blower motor is, it is held up by 3 screws and a wire, one of the screws is a pain to get to the first time you do it. A few days after putting my dash back together after replacing the heater core 1 single leaf created the exact problem you describe.

Damn squirrels, lmao!!! Glad you figured it out and it wasn't anything serious. I figured you might find your HVAC recirc door in there. It's located directly above the blower motor and when it breaks a lot of the time that's where it ends up.
