Sorry to go off topic, but can you tell me more about your loud blower motor noises?
It seems like the front heat/AC blower is unusually loud in our new-to-us 2011. A low rumble starts around the lower-middle fan speeds and increases in volume and pitch as we increase it to full fan speed.
I understand air moving quickly through vents makes noise, but what I am observing is uncomfortable low frequency vibration.
Anyone else experience this?
