In the last six months in my Gen 2 Volt, the AM radio clarity has become terrible while running AC/Climate System in ECO or MAX Mode. The amount of static and noise makes it nearly impossible to hear the radio when listening to AM radio stations. If I shut off ECO or MAX setting (but still leave the fan on) the noise mostly goes away. Yes the stations are distant but the clarity of the station improves as I get closer to New York City (and therefore the AM tower), but it is still very noisy. It was never this bad before. Any idea what could be causing this?
