Dash lights Dim 2016 Via

[D-mac]

I’ve had a 2016 via since June, 21. So Far, I love it. Had to make some discoveries due to operator ignorance, but overall very pleased.
My lights for speedometer and tach only come on after dark. I actually can’t see them in the daytime. I have tried turning the lights to see if they came on in the daytime, but no. Any wisdom??

Has it always been like that, or is this a new issue? What chassis do you have?

Is there a dash light intensity knob or wheel that brightens and dims the dash ligths. Just about all vehicles have this.

I couldn't find the one for the 2017 Sprinter... but it might be similar to the one in this video:

Here's another that "might" apply:

Yes, I would bet it is one of those dash knobs that you've never figured out what they do as you set there in the daylight and can't see anything change! On the older it used to be rotating the knob that pulled out to turn on the lights. On newer it may just be a small roller set in the dash, etc to roll up higher light.
Might be some info in the manual for the chassis? Any drawings that tell what the dash controls do?

When I got it, I had to drive about 5 hrs. Started in sunlight, so I didn’t pay a lot of attention, but as the trip went, I realized it was hard to see these 2 gauges . The information center was bright. As it got dark, they came on and were fine. That’s the question. I turned the headlights on and they gradually came up to bright. During the daytime, whether the headlights are on or not, they don’t come on.

According to the owners manual, there are 2 push buttons on the right side to brighten/dim the lights. They don’t seem to work. I was hoping you guys would know something a “newby” wouldn’t. All the other lights work great. Also, I asked Mercedes dealer if he could fix it and he said that only the chassis was Mercedes, the coach was Winnebago. I haven’t reached out to Winnebago yet, hoping you guys would know a trick

This idea that it's not a Mercedes problem sounds very familiar as I've read a fair number of post of near the same line.
Just as a line to think over, who actually built the dash? Did Winnebago build the speeddometer temp gauges and all that stuff that normally comes on a truck or car?
That sounds pretty nusual to me as I rarely find that on any other chassis that RV are built on!
If you look in a mannul that tells you about how to turn things on and what the gauges tell you, who wrote that manual?

I'm just having a really hard time thinking of a truck chassis being built without all those gizmos that come with the dash and I'm betting the Mercedes dealer is pulling your leg and hoping to never hear from you again! Especially if the chassis had a five year warranty and it's about to expire!

[D-mac]

That’s exactly what I thought. How can the owners manual tell you how to dim/brighten and not be responsible for the lights themselves.

Okay, spent some time yesterday snd have figured out the light issue. I have to turn the headlights on and they just aren’t as bright (as my truck) but they are on and turned up as bright as possible, you can see them.
