2000 Jeep Cherokee

I have am radio noise. Almost sounds like distributor noise I used to get in one of my old cars. A high pitched mosquito noise or whining. Except it doesn't change with engine speed. It comes and goes. Strangely sometimes it will go away when I step on the gas pedal. If I take my foot off, it comes back, then goes away if I use pedal again. And at other times, it just stays constant. Gas pedal has no effect. Do you know cause and cure. Thanks.

H there,

Thank you for the donation,

You will have to check the antenna earth, the radio earth, make sure that the radio PPS connections are ok, check battery earth as well, you may need a radio suppressor on the alternator as well, start here.
