I replaced my radio a while ago and since then the blinkers have not made any noise. They work just fine on the outside, but they make no noise that indicates that they are on. Does anyone know why or what I can do to fix it?

Hi,

The sound of the blinkers working came from the original stereo through the speakers. The system is designed to provide an audible warning through the left front speaker. If you replaced the OEM stereo, that circuit no longer exist.

The new stereo likely doesn't have the capabilities to perform this function. If you still have the installation instructions for the new radio, check to see if there is anything indicated for audible warnings.

Let me know what I can do to help and if this answers your question.

Take care,

Joe
