Hello, new owner of 2008. I noticed at night when I turn on the headlights, the turn signal arm does not light up. Is it supposed to? The arm with the windshield wipers does not light up either. Is it supposed to? On the driver side, the only power window button that lights up is the"Auto" one. None of the other 3 light up even the ones on the passenger doors. I assume they are supposed to light up because they have the little hyphen mark. The "Park" and "Power" buttons light up just fine as does the P, D,R, B knob although it is very dim. Thoughts?
