Prius (Gen 2) :: Radio Controls And Center Display Buttons Not Lit When Parking Light Switch Is Turned On?

Found a simple fix for unlit radio control buttons, cd player opening and center display buttons while the parking/headlight switch is turned on. As it turns out, if the wire connector directly behind the dimmer switch wheel located to the left of the steering wheel is accidentally disconnected, you will not have any backlight for your in dash cd player opening,radio control buttons or your emergency hazard flasher button.

The simple fix is to first remove the left side silver/gray plastic vent cover which is located directly to the left of your dimmer control knob. Place one hand on the top of the vent cover and the second hand at the bottom the vent cover and firmly pull directly out. Second step is to pull towards you the miniature dash panel that the dimmer switch wheel is mounted to.

The arrow tip guide on the miniature dash panel will pull away from 2 guide slots mounted to the main dash panel. Third step is to reconnect the disconnected white male plug to the back of the dimmer switch wheel's female connector. Last step is to push back the miniature dimmer switch wheel's dash panel until it snaps back in place, then snap back in place the silver/gray plastic vent cover until it clicks back in place.
