Try pressing the red "hazard" button in the centre console. Make sure it's in the "off" position.

In my wife's 560SL, if you put something on the console, it will put the switch in a "mid-way" position between on and off. In this position, the turn signals don't work.

Flick this switch on, then back off, and see if you still have the problem.

Even if this isn't the problem, periodically check this switch. I've driven around with no turn signals for a few days before.. the turn signals are too quiet in this car, so you don't know when they stop working!
