I have an intermittent high pitched/frequency noise coming from the back left portion of the vehicle. The noise started so soft that my husband could not hear it. Eventually, the noise became louder and more frequent that he could hear it.
Took to the dealer and was able to create the noise. They replaced the amp. Took care of the problem for about 30 miles. Then the noise came back - although, softer.
The noise is generated most often during the following situations, but not always:
*When turn signal is turned on. The sounds turns off when the turn signal flicks back to the normal position. * Switching channels in XM radio (between each station there is a silent pause, so you can hear the noise more easily). *Turning radio volume up *In the middle of driving on the highway. Radio does not have to be on. *The car has to be on for sound to occur.
Now to top off this whole problem... Today, we drove about 45 miles away from our house. Same noise came on and off about 15 times in our trip. Then we parked the car, it rested about 90 minutes. We drove home and the noise only occurred once (when we turned radio volume up) during our whole 45 miles trip home.
My husband is thinking it could be the capacitor??? What do you think? Has this happened to you?
