Instrument Panel Dimming

We have noticed several times when driving the the instrument panel will dim to levels where you can't really even read the spedometer anymore. It seems to only occur during daylight, and might be related to changing lighting conditions (coming out from tunnel or bridge or something). So, i think its related to the automatic headlights.

My question is, how can i turn the **** thing off or make it so that it quits dimming the dash lights?

Re: Instrument Panel Dimming

Not sure if there's a way to defeat it via settings/preferences.

Sticking tape over the sensor is going to fool the system into thinking it's night and will turn the full headlight package on again and set the Instrument Panel lighting onto 'full on' mode. This will solve your issue with being able to see the Instrument Panel, but the downside is that you'll (a) burn up lightbulb life in your headlights, etc., and (B) suck more gas in the process.

On my Outlook, there is something in the owners manual called "Parade Dimming" whereby the IPC is illuminated fully during daylight and you can't dim the displays when the headlights are on during the day. Not sure if this is a feature on the Traverse or if this system is what's causing the issue.

Maybe try turning on your headlights while you're driving, see if that forces "Parade Dimming"?

IP lights are brighter during daylight, but when headlams come on... due to bridge, overcast, etc, dash lamps dim to night time mode.

Re: Instrument Panel Dimming

Nothing you can do about. It is just the way it is, you will have to live with it. Unless someone knows how to to "hotwire" it. Taping over the daylight sensor will only cause the IP to be dim all the time because it thinks it is dark outside.

Re: Instrument Panel Dimming

if youre pretty sure that the dash is dimming because the sensor thinks its dark outside- and dims the cluster... (and turns on headlights)...
then you can do something about it....
But 1st....
on mine-- it has to be a long tunnel for example- for the dash to dim. (ive seen some BMW's I think whose headlights come on almost as soon as it enters the tunnel) on mine it takes some seconds...

but if you really want them to stay bright all the time during the day--- then youre going to want to change out the light sensing resistor thats under that little dome on the dash.
You will have to pull it-- and measure the resistance across it when theres full sunlight--- and when theres full darkness...
You will then want to buy a resistor with a value close to what the photo resistor showed when it was getting full light..
then you replace the photo resistor with the new resistor...this way the system thinks its always bright outside and keeps the dash nice and bright- all the time...
the only drawback--- is that when it gets dark outside-- you will have to manually turn on your headlights as the resistor will make the system believe that at night-- you still have full sunlight.

heres an image of someone measuring the resistance from a light sensitive resistor... and its output

Re: Instrument Panel Dimming

this 'MOD' was done quite a bit by some other GM owners.
I think by the Camaro owners-
This was for those that didnt want DRL's or something like that.... put in a resistor- and the DRL's never came on. I believe thats what they wanted...

Re: Instrument Panel Dimming

I haven't actually looked, but is it possible to turn off the automatic headlamps where they don't come on in low light conditions? I know I've had other GM vehicles wfere it was possible.

If you rotate the light knob to the left; it will spring back to auto and it will disable automatic headlights; it should also display a message on the DIC to verify
