The indicator timing (as well as the wipers and other things) are controlled by a multifunction relay in the fusebox under the bonnet by the top of the wing. It's the longest large relay in the box. They do fail, and intermittently, but normally give other symptoms too. Be careful when wiggling it out because the plastic base isn't too strong. The pins can make intermittent contact so it's best to clean them before going further.
If the clicker's just not working from time to time the usual problem is a bad contact in one of the 2 large connector blocks behind the speedo cowling. Reseating the connectors usually cures that but you need the right hooks to yank out the speedo with no damage to the trim.

There should be a fuse and a relay for each light. Your owners manual may show it, or you may need a repair manual to find it.

No turn signallights fuse good

IF your indecators are not working none of them then your problem is either a relay or a FLASHER can (the thing that goes click click )every time you switch from side to side, and it should be found under the dash board .
w hen you have found it turn on the key and the left hand indecator and then tap it slightly with a pen or your hand and if it works replace it Other wise unplug it and get it checked out before buying a new one.

Car stopping after gets hot and wont start till cool.

I don't think that all of the stuff should have been done except the crank sensor. The only thing I can see is that the timing is out of wack. I do believe that they have automatic timing control which will automatically set your timing which means that the ECM has to be changed.

Indicators not working on mercedes benz 200 1983 model

If you indeed check and veify the fuses are good than you need to check the relay(s) that control the system. These should all be located in the power box located drivers side firewall under the hood (Black cover). You may need to reference your manual for the relative position of the affected componenets (Fuse, Relay, etc...)
