Welcome to the forum.
Search for Combinational Control Module on the forum. This is an electronic module in the engine bay that among other things, controls the indicator signals. It could be a faulty module, or sticking relay on that module, or bad contacts in the connector, or even the switch in the signal stalk. Some have had some success by turning on the emergency hazard signals which seems to unstick the relays in this CCM, if that is the cause.
This post http://www.benzworld.org/forums/r170...sible-fix.html has some nice instructions that might help.

My '99 slk230 started acting up as well. Turn signals do not blink and they stay on. When I push the hazard lights on, they stay on as well, no blinking. Turning on the hazards didnt seem to reset mine. Where do I start?

Dry joint on fuse holder
I had the same problem with the flashers intermittently not working. I eventually traced it to a dry (i.e. bad) solder joint on one of the legs of the fuse holder for the flasher circuit. This is in the light switch/fuse module in the console next to the steering wheel (accessible when you open the driver's door).
I found it by trial and error after removing the cover underneath the steering wheel and noticing that the movement made the problem come and go. I eventually was able to reproduce the problem by jiggling the fuse.
I removed the module and was able to partially dismantle it (a bit of a mission because it is pretty sealed up) and was lucky enough to just be able to access the joint and re-solder it. I am an electronics engineer and after a couple of decades in the industry I have to say that for a light switch and a fuse holder, this is one of the most over-designed bits of electronics I have ever seen. It is a feat of plastic mechanical engineering and contains a folded flexible circuit board that would win any origami prize!

I have the same problem with my SLK230 -97, the turn signals stays on instead of blinking. since they stay on it cant be a dry (i.e. bad) solder joint.
The most likley explenation i have found is that the turn signal relay is worn out.
I cant find the turn signal relay on my car so i would be very happy i some one could help me and probably many others to.
When you find it you could open it and clean the contact sufaces carefully with a fine sandpaper or just replace it with a new one.
I really hope some one could help us with this.

I had this problem again last weekend.It has come and gone over the past 3 years.There's a detailed rectification procedure with photographs posted on this site that I photocopied some time back.Finally decided to give it a try.The relay is on a PCB located in the black box next to the battery(RHD cars).I dismantled the PCB and cleaned the contacts with a sharp knife,I believe this is better than emery paper for small, sensitive contacts.Also cleaned every contact in the reassembly procedure with contact cleaner.The lights cycled immediately and seem to be fixed,so far.
