I had the car in for a 6 month service, when I got it back there is no illumination in the glove box.
I'm sure there was before. They did pull out the cabin filter to show me, related because of the location?
My CX-3 has a light in the glove box.
The light only comes on when the headlights are on.
It has no on/off switch in the glove box itself.
Even when the glove box is closed, the glove box light shines in the darkness when the headlights are on ;-)
