My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

The led lights usually conflict with the computer controlled operation of the lights as they were not standard lights on this model here.When an incorrect light is detected by an ecu this causes a light issue here.Usually the lights have to be put back to the way they were to correct this issue or resistors put in line to compensate for the LED light style.

As for the no sound issue this is usually caused by a fault with the sound amplifier itself.It usually fails internally causing this fault needing replaced.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
