Climate Control Blower, Making Strange Noise Options

[96stgreendemon]

About 3 or 4 months ago i went with some friends up to a car show about 2 hours away from my house, after a stop my blower started to make a funny noise.
i looked on the floor and there was what looked like pink fiberglass insulation and the fan is making the most god awful humming noise when on high, does anyone know whats up with this thing or how i could fix it?

It might just be that it clogged. Try taking it out and cleaning it putting it back on. Should get rid of the noise. There's all kind of stuff floating around in there and sometimes it doesn't go out the vents but into the blower. & it just keeps accumulating more and more in there.

So im guessing i get to take the dashboard off to do this?

[Imawakeyo]

Nope, if it's the blower motor like your saying it's 4 screws I think under the glove box. All that really needs to come off is the glove box.

Ohhhhh is that what it was lol? I didnt put two and two together because I replaced my heater core bout 2 weeks ago and I have to say its a PITA. Except I had a small puddle forming underneath the glove box which told me it was the heater core . Good look with that bro, if you need pictures or a video I've got some on removing the heater core. Worst 2 days of my life
