I am thinking that it has to be the flasher switch but it does not make sense that right side, front and back, work fine, left back works fine but blinks fast, left side front does not blink at all. Moved bulb to right side as trouble shoot and left side front worked fine

  1. Do you have the correct wattage bulb? correct bulbs.
  2. did you inspect ALL sockets for corrosion ?
  3. want to make sure if you swap left to right does it flash still fast or no flash knowing that the left light is good?

Thanks

I switched from left bulb to right and all turn signals worked the same, left front still no blinking, left year blinking fast, right side works fine, scuffed up contacts on left signal and pulled striker plates forward a little, no change

For the cost to get an answer, I think I will call German Auto where I have had work done before and ask them some questions and probably take it in
Mercedes Mechanic: Wolfgang, Mercedes Technician replied 1 month ago

how about the whole assy? did you swap. easy way to see if it is the whole light assy that is at fault.

note you said

Right Front Turn Signal does not flash, getting fast blinking rear turn signal,

then you said

I switched from left bulb to right and all turn signals worked the same, left front still no blinking, left year blinking fast

so its the left side you have an issue correct?

Ask Your Own Mercedes Question
Customer reply replied 1 month ago
left side only. Rear blinks fast front no blink but the bulb works for park lights so I wonder if a flasher switch would work to activate three other bulbs and get nothing from the right front. Makes me think it is assembly. Then I will leave to a professional at German Auto
Mercedes Mechanic: Wolfgang, Mercedes Technician replied 1 month ago

no the flasher would do all bulbs at the same time so it would not be a flasher.
