High pitched tone under hood when car is off
This just started yesterday. Got home after a day of driving, pulled into garage, turned car off and we could hear a high pitched tone coming from the front of the car. Sounds like a whistle. Opened the hood, didnt seen anything. Noticed the sound was loudest when I put my ear down in front of the grill by the subaru emblem on the front of the car. Any ideas what this is? I have seen posts suggesting vacuum hose, but those posters said their car was running. We don't hear this when the car is running,, but maybe because the sound of the engine is too loud. The only way to stop the tone last night after it went on for a couple hours, was to disconnect the battery. Figured it would only run down the battery if left on. Any help is appreciated. It's an 05 Forester. Thanks.
