Rear view mirror light - Mercedes E550

melissa561 • 15 August 2019

I had my start button replaced. When I click the unlock button on my keyfob the rearview mirror light turns on and stays on when the car is running. I cannot get it to turn off. Does anyone know what this might be from? The rear view light turns off when the car is off. Thank you
