Yes, there’s a backlight for the LCD cluster when the car lights are on. There’s a bulb at the bottom of the ACC unit. Use the same tools to pull the radio to pull the ACC unit. Then a quarter turn with a flat blade tip releases the white plastic bulb socket.

The unit that came with the wagon won’t light even with a good bulb. I got a replacement unit at the pick-n-pull and all is well. No programming, no introduction, just plug-n-play.
