I have this issue and wonder if anyone else has this. During the day if it rains and the auto wipers come on the headlights also turn on (that's normal), but the dash lights dim like its night time and you can barely see any of the gauges and the radio settings.

Auto wipers/headlights and dash lights

OK.... Thanks... We have a 2021 Durango Citadel and it is smart enough to do that... so I was wondering why the RAM isn't.
Well that is cool.
Could be onto something here on adjusting this for Rams. Your Durango uses the same sun sensor as the Ram. Any chance you have AlfaOBD so we can see what the day/night voltage thresholds are set to on the Durango?
I do have it and I can absolutely do any testing you need done. Just let me know what data you need.
Just need a copy of the Durango BCM settings. Connect to the body computer with AlfaOBD.
Click on the battery icon in the lower right.
Click read system ID, and let the list fully populate for about a minute.
Go into tools up top, and upload the “body_chrysler info” file to google drive, and post a link to it here (or PM me).
A security gateway bypass does not need to be installed to get the read on the BCM.

You know you can rotate the dimming knob all the way up to turn the screen and instrument panel back to daytime lighting right? Or is it you don't want to have to do that? And I think you can turn off headlights with wipers....
OK.. getting that info now.. just got back from a trip....
I'm aware of what you can do, but the whole purpose is why do I have to? I have another Dodge vehicle that works correctly (no dimming with wipers during the day). So if it's just a simple value that needs to be enabled, then I want to get that enabled.
Just a follow up on this. I made a complaint to FCA about this issue and I have been assigned case number and have an appointment at a local dealer to work with FCA engineers. I'll keep you guys posted about any outcome, but the folks I was talking with did mention that the vehicle should not be doing this.
Could just be nothing that FCA will do but I also made a claim with NHTSA about the reduced dash visibility.

Here is the FINAL word from Ram Customer Care:
They are now aware that this is an issue. A supervisor with level 2 (Jim) said he will make the notes and also send the concern to an engineer he knows at RAM. No promises, but he will let him know that the fix should be an easy code tweak and that it might (or might not get done) in the future.
All in all I felt good about the discussion I had with Jim (talked for about 45 minutes). Consider this topic closed (for now)
