Sitting in my 2007 Fusion SEL (5 speed manual, 4 cylinder engine, automatic A/C - if that's all relevant), I have starting noticing a chirp that seems to come from the center IP or from under the glove box. So far I haven't stuck my head down there to see exactly where it's coming from. It's not the blower motor spinning though it may be somehow related to the blower motor. The sound occurs at 2-3 minute intervals while the car is running or when the key is in the "ON" position. I was guessing that it was another of the car's characteristic "fuse popping" sounds that I hear when I activate the wipers or other electrical components. Does any one have a definitive answer? THANKS!!!
