C300 rear blinkers in different spots.
Where should i check first? Sam module? Wiring harness? ive been asking in facebook groups and no one seems to know. Can provide pics if needed.
Mercedes are exceedingly temperamental when it comes to electronics.
mercedes wanted 850$ to replace the earth wire to stock wiring, cheaper to replace taillights and do wiring myself, especially since its such basic wiring.
the recall was for the harness and bulb carrier, i got rid of the bulb carrier and bypassed the ground wiring fault by wiring earth to earth directly into each other instead of thru the harness,
the problem in my blinker has persisted thru oem and aftermarket tho, could it be the wiring isnt matched up in the harness or do i have a faulty sam ?




I watched a little of that video but still not sure exactly what was done to YOUR specific set up. Photos would be good.
I would remove everything that does not belong, or come stock with the car. I would put the original bulb carriers in, or buy new ones. Im sure inexpensive mercedes clones would work also. And install new harnesses. They can be found cheap.
Im also sure we can get those aftermarket tail lights working, but would need photos to see what is even going on.
