Radio/Screen Dim with Lights?

skunkstripe · February 11, 2014

I have the 8in screen. And i was wondering if it is supposed to lighten and darken. As it gets dark and lite outside.

If I understand what you are inquiring about, the radio face does get brighter and darker depending on the outside lighting conditions. The sensor on the dash will turn the headlights on or off and therefore, your radio will be brighter or darker. Does that make sense?

That is what I have noticed as well. Took a long drive through some wooded areas this weekend and noticed towards dark it changed back and forth a few times until it was dark enough to stay put. Sometimes I think these trucks are "too smart"

If the radio screen is not doing this, you can program it to do so via settings.

Thanks for your help. That is exactly what it is doing.

there is also a scroll wheel by the headlight switch that allows you to adjust interior gauge illumination when the headlights are one.

I have a 2016 Acadia. Today the dash lights and radio screen randomly kept going dim and it had nothing to do with the light or where I was driving. In addition the voltage also fluctuated, but not every time the lights went dim. I also had a brief issue with the rear heat/ac button a few weeks back. It suddenly came on so I turned it off and it then came back on by itself at least 6 more times in about a 10 minute span. It happen again the next day 2 or 3 times, but I haven't had the issue since.

Old posts I know but can't find anything current. I have the exact same problem on my 2013. In your case I would check the grounds from body to frame under the driver's side cab. Also look for any other bad grounds, clean your battery grounds maybe even add a battery to body ground.

Does anyone here have a 2018 or newer with the 8inch display? I want to turn the display off at night. Dimming it sometimes isnt enough. Problem is when i turn it off it doesnt stay off for more than 15 or 20 sec before it turns back on by itself. Just wondering if this is normal or if my display has an issue.

My radio light keeps changing from bright to dim at day time a few times in a 35 minutes drive

Daytime: should be full bright.

Nighttime: should dim down, depending on where your dimmer switch is set.

There is a mod that can be done to make it dim even further, still controlled by the dimmer switch. I had it flagged to "follow," but now it's not in my list.

My 2018 Silverado does this : As I drive it during daylight hours the display will periodically go dim to the point that I can't read the display very well. Then as I continue to drive along it will brighten up again. The service person at the local dealership told me that the light sensor is being blocked by my dash cover. So I made the dash cover hole bigger so that there is no way it could block the light sensor. It wasn't blocking it before anyway. This mad no difference and the display still dims on its own.

Anyone have any ideas??

Thanks

It may not just be the cover. For me, as summer comes in and the trees fill out, the auto headlamps go on and off way more often than fall/winter. This is one thing where Chrysler stuff has something that I'm shocked no one else copies- you can easily override the interior dimming with the dimmer switch and they have a dedicated screen off button. It's like three screens deep to turn off the screen on our trucks and that's silly.

Well, I've tried to compare my screen dimming to the auto light dimmer function and it doesn't seem to make a difference. You can turn off the Automatic headlamp function with the light switch, which I do, but it doesn't affect the dimming of the screen display. Cloudy or sunny days don't seem to affect it either. It just goes dim, then randomly it will go bright again. And then randomly it will go back to dim. Or sometimes it will stay bright and not have any issues. But guaranteed that if I need to see something on that display, such as a radio function, or phone function, it will be dim and I will have to wait for it to go bright again on it's own.

I guess it's just that the electronic controls on these new trucks just think that they are smarter than we are.

And don't get me started on Chrysler/RAM products....I have one of those too. Ha!
