My heater or (fan) screams at me.

[Z28]

I'm not sure what's wrong i guess. Do the fans just go bad or what? After a few minutes of driving i get this loud howl from the passenger area under the dash and i stop getting air.

If i turn it off and back on immediately it goes away but comes back in a few minutes. If i keep the fan speed lower, it does it do it as much but it still does it. If i have it cranked up, well that's not even possible, it just stops and howls at me.

I was hoping this is a common problem and i could fix it easily. I searched but got nothing...so wtf is making that annoying scream.

Sounds like bad bearings in the blower.

[chrisb]

yeah bad bearings sounds right. mines squeals some times and sometimes goes away, mine was cause from water going through the fan

[Z28]

is there a how to somewhere? how hard would this be to replace

[chrisb]

im not sure where the blower motor is on a camaro? on a grand prix its underneath the dash on the passenger side and i think theres three screws that hold it in thats it

[Z28]

i'm sure you are right, cuz thats where the sound is comin from...and yes i was referring to the grand prix. probably should of mentioned that but i usually try and stay on "grand prix" topic when i am here.

it's about -5 to 5 degrees here every day so i haven't really looked at what im dealing with, just trying to scope things out so when it gets warm i know what i am dealing with

thanks

I swapped out the blower motor. If anyone needs advice on how to change it, just ask me. It was rather easy. I took my time and it took me about a half hour to do.

Works perfect

Yeah it sounds like the bearings are making noise and seizing up the motor. Get a new one, that should solve your problem.

[Sparg93]

i have the same problem, should i replace the entire blower motor, or is there a way to grease the bearings...or just replace the bearings?

My 2007 GP Base does this but only when I'm going 60mph+ and having the A/C on or off doesn't matter. It howls just the same. Is there a specific solution to this noise? Or some specific things I can try to fix it?
