Starting at about 15mph , coming from the firewall/glove compartment box area there is this kind of chirping/almost rattling/whistling sound. It's kind of hard to describe the sound exactly. But it will start when I press the gas and am at about 15mph and then continues until I get below 15mph and it stops. It only occurs while in motion, when i'm stopped , nothing. Only once I get passed that 15mph mark will it start. It sounds like it's behind the dash near the firewall in the general vacinity from the heater/HU console area and over to the glove box area. It's kinda hard to pinpoint exactly where since the car has to be moving and I can't really lean over to listen closer... any ideas of what this noise could be?
