Hey guys! my passenger side fog light decided to go out on me a couple of weeks ago, and i had replaced it last week even though the bulb didnt look burnt out. The driver side is still working perfectly fine. Today, i tried turning on my fog lights on and the passenger side went out again, and the bulb didnt burn out!

I also took the white part that connects the bulb to the fog light wires and put it on my driver side and it works. what is wrong! thanks in advance guys

one thing you gotta do is switch both fogs and sockets to the opposite side. remember the benz computer wont turn a new bulb right on when plugged in, you must cycle the key completely off and also cycle the lights, then u can check it. If you have a blown bulb and replace w a new one it wont light up right away! MB go figure

 

I hahve the same issue but after putting ina new bulb nothing. I have had 358 views with no help or answer. I put a test light on the wires no power but I dont know how to test further. I know this must happen allot but no help out there..

 

I'm having the same issue. Swapped the bulbs and sockets. Everything worked on the left side (both bulbs & both sockets), nothing worked on the right side. A day after putting all components on their original location, the left side disabled. Any info...link to an applicable thread?

 

Are you sure that this is not the cornering light function working as designed? The lights will cycle on and off based on the steering wheel position.
