A few days ago my warning chime started sounding through the ipc instead of the speakers. Did a little research on the forum here and found out it may be caused by a bad speaker. Did a little testing and sure as ****, the right rear speaker wasn't working at all. Youtubed how to remove the rear door panel and the speaker is open. 36,537 miles on it today. Had an appointment yesterday for a driveline noise and mentioned it to the tech that it started doing this but I told him not to worry about it. Drive line noise was diagnosed as a bad ring and pinion. Hard to brag about my Ford when this kinda **** is happening. This forum has been great for helpful information.
