CLK430 Interior lights flickering
I have been having this issue for a while, I suspect a ground but I don't really know where to start with this issue. I get pulsating/flickering from the interior cabin lamps, primarily the instrument cluster and the climate control display unit. The battery is good, the alternator is new and the voltage is a consistent 13.8-14.3 depending on how many accessories are running. I've poked around under the car a bit, I just replaced the ATF this weekend with the last of my Titan 3353 (236.12 spec) and was unable to determine the root cause. Aside from the odd flickering, the car runs perfectly, it only has 60k miles currently.
Any suggestions as to where to hunt this issue down?
Thanks
