My 2010 is dark on the 1) on-off button and 2) all of the buttons controllong the radio. Is the light source for all of this the "illumination, button part # 39107-TA0-A01" or is are there different sources of illumination for the button and the radio control buttons? I will be removing the entire console to change burned out bulbs for the HVAC controls and so I want to tear this apart one time only.
