After having some control arm work on the same side, the right front turn signal remains turned on, full time, and does not blink. That means it stays on whether the engine in running or not.

The rear signal is working normally and of course, the issue does show up constantly on the computer.

Just before this happened, the signal was not working and i replaced the bulb. itwas a matter of minutes / hours before it started this, always on issue.

Next, I have tried the left bulb and holder on the right with the same holder and I get the same result. The wiring and plug all seem to be in fine shape.

So, has anyone had this problem and found a solution? as this problem have to do with the turn signal relay?

 

What year and model is this for? If it's an OBD2, have you pulled the codes off the DTC?

 

This is a 2005 model C230 Kompressor. I do not have a code reader. The only indicator is on the onboard computer read out shows that there is trouble with the right front turn signal.

 

If you're able to bring it to an Autozone or similar store, they can likely read the codes for you which should give you a definitive place to start looking - I agree with you that this can likely be the relay.
