Bdash4

I have a 2014 C class BLUETEC c250 and just noticed that the front turn signal is not working. The DRL and the headlight works fine, it's just the orangy turn signal leds that won't turn on. The turn signal on the wing mirror and the back are working fine and there is no fault shown on the dash.
Any recommendations on what could be wrong and where should I start looking?
Note: not sure if it matters but The car was idle for a month and it snowed for few days.
