When I'm using my heat, I hear a vibration-like noise (there is no vibration, just noise) that seems to be coming from the passenger side under the dash.

The noise can be fairly loud and is definitely tied to using the heat. It seems to subside or go away when accelerating and then return when stopped.

It's been a few months, but I don't recall this happening using A/C. Any help you guys can provide is very appreciated.

Could be the blower motor. Does the noise go away when increasing the blower speed? The blower in my '02 makes a chirping squealing sound when first turned on and at low speed. The noise goes away by increasing the motor speed.

 

It does seem to quiet when it's running at a higher speed, but I couldn't tell if it was actually quieting or being muffled. It does sound like a motor.

Is this a sign of something bad to come? How extensive a repair?

Thanks again.

 

If it is the heater motor the noise is caused by dry bearings and will only get worse over time. I would say replacing the blower motor is a moderately difficult job, only due to the parts that must be removed to get to the motor accompanied with the awkward positions the human body must endure.

 

mine does it on cold start but goes away promply, from what Ive read (on here or on swedespeed? do a search..)you can try to grease the bearings but it will only be a temporary fix, youd have to replace the motor, either way the glove box has got to come out.. then there is like 4 bolts holding the motor
