I am driving a B180 (W246) 2015 model. I am experiencing front right blinker light intermittent not working. The right view mirror blinker is working. The rear right blinker is working. When i turn on the hazard switch, all blinker lights are working except the front right blinker light. The front right blinker light is integrated with headlight, it is LED. The are no bulb to replace. Would like to seek help anyone have the same experience. Appreciate if you can share what is the main cause of the fault. Thank you.
