Dashboard lights turn off when I turn use headlights
I have this weird thing happening with my 2010 Yaris (4 doors, manual transmission, no powerwindows, cruise control, etc).
When I twist the headlight knob to turn on the headlights, all the instrument panel light turn off. So, when turning on my headlights (at night), I can't see my speed, radio, etc. If I bring it back to the first position, the instrument lights come back on.
