Anyone else have this symptom? I'm getting a growling noise when I turn on the AC. I only hear it when the fan is at 1 or 2 due to high air noise from vents at 3 and 4. I seem to hear it in city driving when accerlerating/increasing rpm's. I don't seem to hear it when at constant speed. It make a sound like a when a fan rubs against its housing. Idle seems a little rougher too.

It could be bad bearings in the fan motor.

 

Abbid: What mileage did your AC growl start at. How many miles have you put on it since you took it to the dealer?
