So I finally got around to fixing the soft close problem on my wife's s55 and thought I'd fix the inside handle illumination I just happened to have 8 blue 12 volt chip LEDs left over from another project so I proceeded to replace the bad led with the upgrade and wow pretty cool so I did the other three doors. Then i did all 4 doors on my s55. Now here's the problem only the front two doors on wifes 2005 s55 work, none of them work on my car and back doors on hers I verified the polarity on the new LEDs and tested all the old leds which all were bad. I looked in all the modules for coding, I can't locate any switching circuits. I assume they are powered from their respective door control modules so what are the chances all these modules are bad and only the door handle illumination circuit. What am I missing?
