Hello,

A whining noise that is coming from your vehicle's speakers is caused by a failed capacitor[s] that collect the Electro Magnetic Frequency[EMF] that is produced by the ignition coils. The capacitors capture the EMF and safely run it to a ground so the EMF doesn't bleed over into electrical wires and disrupt the operation of your vehicle, or the stereo. In the diagrams down below I have included the engine management wiring diagrams for your vehicle with the radio interference capacitor circuit high lighted for you. Please replace the radio interference capacitor and get back to us with how everything turns out.

Thanks,
Alex
