Dimmed Backlit Dash and Radio/HVAC Lights

Right, the dimmer knob (or shaft) works day or night. At the end of the rotation the dome lights turn on.
My problem is that the dash lights randomly dim themselves without my touching the dimmer,
When I say randomly, it's just that. It could go many days and then dim and come back to the setting 5 or 10 minutes later. It's not like it's constantly flashing dim and bright.

Just checked mine. No dim at all in the daytime.. What would the issue be?

Do you have anything on your dashboard? I’ve found with other vehicles that an obstructed auto-headlights sensor by means of a dashboard cover or even dark tinted windshield can cause dashboard lights to do some weird things including dimming all the cluster and control lights in the daytime intermittently.

dimming is usually affected by the sensor on the forward part of the rear view mirror on drivers side
put your finger over it and the lights will dim
most likely would not be the cause for flickering or any other weird stuff though, unless you had a air freshener or a sticker or something obstructing it
