Hi folks. I tried searching but couldn't find anything similar. I have an 07 EX Coupe AT. As its started to get colder, it's starting to make this strange humming sound. I'll try to explain, but it's weird. It only happens in the morning when its cold out ( < 35). When I put the key in the ignition and turn to where the radio and stuff comes on, there's this humming noise that seems to be coming from somewhere behind the little cubby hole underneath the HVAC controls. It's relatively loud (can be heard with radio on). It sounds almost like an electric motor dying, if that makes any sense. The sound continues after starting the engine, but stops after a minute or two. Almost as if it's "warming" up. Then, it won't happen for the rest of the day. If its not cold in the morning, no noise. Any thoughts?
