I was driving my 2012 ML 350 About a week ago and I tried to turn left with blinkers but the blinkers didn’t work. The “blinker stick” works perfectly fine but the sound when activating the blinkers doesn’t make a sound. When I put Hazard on, it works perfectly fine. I am asking you all because I don’t want to spend money on a repair just yet.
Do the actual blinker lights work? I assume so. If the lights + sound only work with the hazard button then it’s a problem with your blinker stalk. If the only problem is it not making sound when you use the blinker stalk but the lights work normally, honestly I don’t know. Maybe a software issue?
