What would cause a continuous buzzing from the passenger side door speaker?

(2011 Ford Explorer)
When the ignition key is on there is a buzzing sound from the door speaker on the passenger side, even when the stereo is turned off. It comes and goes while driving. I changed to speaker and checked all visible connections, but it did not fix the problem.

2012 Ford Explorer having the same exact issue. Passenger door speaker buzzing to the sound of the alternator. Appears to be a wiring issue that Ford should fix considering it's happening to so many of us.

Feedback from the radio, find a radio repair shop there in Potwin, Ks. Must be a big place, a lot of people are from there.

I have a 2012 Explorer doing the same thing. I figured out that if my wife puts her foot on the carpet right next to the kick panel on the passenger side it will make the noise go away. I pulled the carpet up and there is a big main body harness right under the carpet with a few connectors. I can't find a frayed wire, but it could be a bad connector. Anybody ever get this fixed?

I have the same issue with my 2011 Ford Explorer XLT. The passenger side door speaker makes a buzzing noise, regardless of whether the radio is on or not. It has been getting worse lately. Also, going over bumps in the road can make the noise disappear, come back, or change intensity. It sounds to me like a wire is grounded or frayed, because as the engine RPMs change, the frequency of the noise also changes (the speaker noise goes to a higher pitch as the vehicle accelerates, and vice-verse.

I have the same problem. Did you ever find an answer?

not a repair but more of a question: mine seems to happen when I put the window down and up a couple of times. Then when it does start humming and I put the window up and down the noise gets worse. But if I shut the car off for about an half hour the noise goes away. So I think it is something in the power window motor that is back feeding into the speakers.

My 2011 Explorer is experiencing the exact same problem. The Ford dealer replaced the radio and right front passenger speaker last December to try and remedy but the noise returned shortly thereafter. The noise is intermittent and will go on and off after hitting bumps in the road. The car is presently back at the dealer for further diagnosis. I did seem to notice a correlation of the noise happening more frequently when there was precipitation. The dealer was going to test that theory as well. Based upon the feedback in this forum, the problem does appear to be systemic. I hope Ford addresses this problem for the consumer.

Also having the same issue. Jiggling the key in the ignition while the buzzing is at it's worst changes the pitch and intensity of the buzzing. With all the electronically controlled systems in these trucks makes me fear for my and my family's safety. Dealership offered no help. Driving my Dodge Dart until this issue is resolved.

Same issue on my 2012. However, noise will stop when right rear door is opened and closed with force. But, eventually begins again. Have noticed it more when weather is warmer. Has anyone found solution yet?
