Sunlight sensor things it's night when it's not

[Stingraynut]

For a couple of years or more the light sensor has been getting worse and thinks it's night when it's day. This means I can't read the infotainment screen and it's impossible to see anything on the reversing camera screen.
Is there a way I can fix this?

Try this. I did this mod a month ago and it's transformed the operation of the ambient light sensor in a positive way.

The problem: To those that don't want to read this whole mess of a thread: The light sensor is the little hemisphere sticking out of the middle of your dashboard near the windshield. It has three functions. Lighting up red when the alarm is on, giving feedback to the auto-HVAC system and...

Thanks very much 3rspecB, that's well explained.
Unfortunately there are 2 pics missing, linked from Sheffield Steve. Were they of the goop? does it just wipe out or does it need kero/metho to clean
?
Re leaving out the middle speaker, I know that in the sportswagon they left out the sub woofer, which is a shame, have you noticed missing the center speaker or was it an improvement?
and did it make any difference to aircon.heater?

Centre speaker went back in place. I only removed it to get to the ambient sensor in/out. I used isypropol and carefully removed all the white goop with my fingers and cloth dipped in isypropol. My air con temp is used manually, I don't use auto setting so can't say if it's any better or not.

I did this mod last year. Didn't need to remove the speaker grille. Just popped the sensor out. I only removed the goop covering the ambient light sensor as I use the climate control in auto mode. Auto lights and dimming has worked perfectly ever since. Lights no longer come on when the sensor gets shaded momentarily by a tree. Very happy withe result.

Holden sourced this part from the US. So they didn't modify for Australian conditions.
