I have a 2005 E320 sedan that the front right blinker does not work. The bulb is good and swapped the sockets and it's good. All electrical works with the exception of the right front blinker. Before I remove the bumper and swap headlight assembly's does anyone have any suggestions. Thanks for any help

Did you test for (+) and (-) in the socket itself?

Not yet.....that will be my next step. Not sure if this is a common problem or something I need to slowly rule out by trial and error.

The sockets are known to corrode. I don't think they're that much either. There's a youtube video on how to do it, but that might be for the facelifted model.

I had a similar problem, although the bulb flashed normally the dash indicator flashed rapidly as if the bulb was bad this was on and off for around a year. I finally brought it to my independent garage and he said MB had a fix for it and rewired the socket back into the wiring harness and its been good for over 2 years now.

I am having same problem as @algeria , turn signals flash normally, but dash indicator flashes rapidly when right turn signal is on (left is normal). Very strange... I guess I'll look into the socket and harness.
