Auto headlights sensor sensitivity

[r50loverPR]

I just got new tints for my pathy and I'm noticing that in the mornings the auto light sensor is turning on my headlights when there is already enough sunlight out, just curious if you can adjust the sensitivity for them. If not then I guess I got morning-time running lights then haha

Make sure the sensor is not dirty or dusty, it's right there on top of the dashboard, near the windshield. There's a sun load sensor for the AC and the light sensor for the headlights.

 

If it's scratched (e.g. when cleaning the interior) it can also trigger sooner as it's perceiving less light. You can use Meguiar's PlastiX or something similar to remove the scratches.

 

I don't think there's a way to adjust the sensitivity unless you tweak the resistance values by intercepting the signal/wire. The service manual must have the low/high values for that sensor.
