A couple reasons that might not work:
1. The sensor but on a different circuit is also used in averaging the interior vs exterior brightness for the auto dimming rear view mirror and I didn't want to effect that operation.
2. Turning it around wouldn't change the fact that if it's not averaging "properly" because of the frequency of being in a shadow, frontward or backwards it's still gonna be shadowed.

Thanks for the post. Seems like a lot of work for a GM problem that mostly everyone is experiencing.

Home Depot sells light sensors for wiring porch lights, wonder if we could use that instead of a switch. Basically adding our own sensor to it that has better sensitivity. The vw golf with standard lights has a mod that uses an aftermarket adjustable light sensor. Pretty inexpensive. Could work to.

Definitely interested in this mod. Can you do a quick walk though on how to remove the dash?

Like you wanna do it from the top and have access to the full length of the sensor harness or you just want to get to the area near its branch from the main harness (where you can splice into) that I show in the pic with my finger?

I just want to install a switch the easiest way possible, so do I just need to get to the branch area?

Yeah.


I think I followed someone's radio removal. Basically just pull the trim off from around the radio/hvac controls.

Basically what's shown in the first pic in post 4 here:

Interior Trim Removal

You may need to remove the MyLink screen but thats pretty straight forward. A couple screws they were obvious if I remember and then some connectors on the back.
Since I had everything apart, I don't remember if you actually have to remove the MyLink display or if you can see the wiring without removal. It will be very near the upper left corner of the display in either case

Scariest part was pulling that faceplate/trim off.

What gauge wire did you use, and where did you mount your switch? I assume down by the cig charger?

Ummm don't remember but I think it was 18awg because I don't usually buy anything smaller. Factory is really thin, like 22-24awg so as long as youre bigger you wont hurt anything.

I actually wanted it close to the light switch since I wasn't gonna label it and that kinda makes it easier to remember what it goes with.

I mounted it low on the kick panel below the light switch but down a ways closer to the OBD connector and hood latch. Close enough to feel to reach but not so high and it's terrible noticeable, I don't think I took any pics

I used the little round on-off switch I posted earlier (no lights, I didn't want anything to potentially affect the circuit voltage or be a distraction) but mounted it as a horizontal toggle rather than a traditional up-down.

The way I did it is left is closed - normal automatic operation which corresponds with the light switch "auto" position being on the left. Right would be open and thus full bright which corresponds to the light switch "manual" mode being all the way to the right. This way I can tell by feel where it's at.


PS. Do it however you want. I probably over thought all that LOL

Ambient Light Sensor Override (Take Your Brightness Control Back)

I'm not sure why GM makes this so difficult. This stuff is all computer controlled, we should be able to adjust it on the fly. I'm no toyota guy, but the cheap rental I had the other day had an adjustment right on the infotainment screen...

They could also add a 4WD indicator to the DIC screen through software, but that's a topic for another forum.

I haven't noticed an issue with this on my 2017. But it's an interesting hack none the less.

How do you get the outer frame around the stereo off man? I tried prying it, but I felt like I was gonna break it so I just gave up.

Yeah it's supposed to feel like that. Just pull, it's hella scary but try to do it carefully but firmly

You can see the clip locations in the pics from Kokiri

even mazda is light years ahead of GM on electronics like heads-up displays, more fine tuning adjustments in the DIC including rear camera view adjustments. oh yea the asians are more educated than americans

^^^^Y'all, are you even sure those settings in other vehicles control when the interior lights dim? They appear to be the Headlight settings. We're trying to control out interior lights here. So it think yall are off topic a bit

How is talk of automatic headlight settings off topic? The interior displays dim because the headlights were turned on, because the truck thinks it's dark. You wouldn't want your interior displays being at full brightness at night, so the system dims them at night, when it turns the headlights (not daytime running lights) on. Confused about your confusion.

Ummm nope pretty sure they are not linked. Since even if you turn them off manually the interior will still dim on you when it perceives it "should be" dark

Try it for yourself, manually turn your headlights off and watch the interior will still dim on you

You can even see the interior brightness dim if the truck isn't even on. Sit in a parking lot with the front in the shade and it full daylight out. Your interrior will dim so that you can barely see it even with the truck off.

I haven't tried again yet. I'm too paranoid that I'm gonna break it. Worse yet, I have a new rattle occurring while driving because of trying to pry it off. Pissed. 😡

That sucks

When I pulled off the lower cubby (separate project) the last time it was on so tight that 2 of the clips literally flipped themselves inside out. Needs less to say there is no reason that little cubby needs to be held on with 6 clips. It's barely even big enough to fit all of them, so those 2 went in the trash and it's plenty secure with the other 4.

Point being that since you tugged on it maybe you loosened a clip or 2, since they can deform, and the trim is loosened.

You do have a plastic trim pry tool set right? Try putting a few layers of blue tape on the dash that will help protect from gouges where you need to insert the tools. Try to pry near where the clips are to be most effective at popping them out.
