1994 E320 turn signal
 

I am having a problem with my right turn signal. Hazard lights, horn and wipers all work fine. This problem is only affecting the right turn signal, all fuses are good and I have checked the bulbs by swapping them out. The combination switch has also been replaced. My question is can the N10 relay cause only the right turn signal to malfunction? Is it possible to resolder or is a new one needed? The N10 relay was making a buzzing sound when I would try and activate the right turn signal, in any case it still wouldn't flash or illuminate at all. I could use a little guidance. Thanks in advance for the help.

Just replace the relay, they are a dime a dozen.

+1 ... The relay is most likely the culprit.
