Insrument cluster plug question
2001 ML55AMG 4JGAB74E71A229618
Does anyone know what pin on Instrument cluster responsible for light on the cluster.
Iooks like not enough voltige going to the 4 bulbs that light the cluster up when i turn the headlights on. Bulbs are good, and dimmer knob looks like its working when i turn the knob it goes darker and lighter but i would say it lights up about %25 out of %100 does anyone know what it can be? or point me in a right direction. Thanks in advance

You or someone else changed the illumination settings. Read pg. 80 in your owner's manual.

I am talking about the 4 bulbs that are inside of the Cluster that light it up. But Temperature millage and clock lights up good.
My headlights are not connected at the moment, but i dont think that would have anything to do with it?!
Unless i dont understand the page 80 and there is a programming procedure to it.
Why i wanted to know what pin on the plug controls the cluster lighting, wanted to measure it with a multi-meter see how many volts coming in up to it, if its possible

Hi, the Knob (1) that illustrated on page 80 is all the way to the right to the highest setting and bulbs are very dim you can barely see that bulbs are on when i turn the headlights on.
