Is there supposed to be a backlight for the headlight switch so that you can see it at night? I thought those controls used to be lit so that you could easily see the knob to turn on the headlights/parking lights/or auto function as well as the dimmer switch for the dash and interior lights. It is no longer illuminated and I asked about it at the dealership. First the guy said it doesn't light up, then checked and agreed I was right, but they had to order the part. They replaced the part yesterday and last night while driving, still no backlight on the switch. Am I remembering this incorrectly, or is it actually supposed to have a backlight at night?
