My girlfriend has a 98 civic and the blower motor makes an awful noise when turned on at any setting. Of course the higher setting the louder the noise. It doesn't even blow at this point, it just makes the noise. It sounds like the fan is rubbing on the inner housing. Is it possible that the bearing went bad and the motor needs replaced? Or has anyone had this problem before?

You'll need to get the motor out and inspect for debris, like small twigs and/or leaves.
If there's anything caught in there, dump it and clean the intake screen under the hood (near the back by the windshield bottom)
If there's nothing in the blower motor, you'll likely need to replace it.

Good luck!
