2003 CLK 320
Headlight issue/help with troubleshooting

Hey there w209 tribe members,

I haven't logged in some time but still have the CLK in the family of cars. The CLK has 160k miles and counting. I am hoping to keeping this car until north of 200k. The trouble I am having is with the low beam headlight. I previously had DEPO's installed from fishcake a couple of years ago. The passenger headlight went out recently and I have been attempting to trouble shoot it. I purchased a new bulb and it is still not getting power. Next, I purchased a new set of headlights thinking it could have been faulty wiring. Upon receiving a new set of headlights, still the same problem; all lights work (high beam, signal, parking) except low beam.

My next assumption is that the wiring on the MBZ side went bad but before taking the plunge to figure out, I wanted to come here and ask what you all might think is the problem and if there are any troubleshooting steps I may have missed.

Thanks,
Brian

Own 2005 CLK500, but drive 2011 Sienna :)
I would probably start with the multimeter checking the wiring.
