    High pitch low volume sound ....driving me crazy

    Hi guys
    get a sound most of the time with key on and running
    its a very low high pitch noise , I think it comes from the back of the ashtray area. When I put the radio on it gets louder .
    car is a 94 E500
    thanks guys

    Does it sound like electrical interference? Maybe a video would help

    Yes it sounds like interference , noise it to low to hear on video its really high frequency. I removed fuse #9 (radio)
    and it went away I have a feeling its from the radio
    nouse is there with key turned and when I turn on the radio the noise changes frequency
    is there an amp in the 94 model? If so where?
    noise is near the radio/ ashtray area
    thanks guys
