W140 S320 Interior Light Issue
 

Hey everyone,

On an 140 S320, what would cause the interior lights to not function? (Dash, and back lighting type)

Excluding all the easy normal things, like fuses, blubs, instrument cluster based things.

One of the mechs at my shop asked today and I pointed him towards this place and figured someone on here would have some ideas. I've never owned/worked on a 140 so aside from the normal I'm not sure.

Thanks!

If it's not the fuse or bulbs, it's the switch or ground points.
Are all the backlights off?

If you mean JUST the dash, not the dome lights, then maybe it's dimmed down all the way??

I dont quite remember the entire problem description. I did point him to this site so maybe he'll find a solution.

I assume he checked that kind of simple stuff, with the dimmer.

It is a little strange on that model, the +/- buttons on the side I think? Might depend on the year, which you haven't mentioned that I've noticed, anyways.
