I have had my "new" '07 TSX for 3 months now. Out of the blue I lost all of the backlighting on the buttons for both the Radio (non-Navi) and Climate Control. The dashboard dimmer still works and even dims the wording for the Hazard button and Passenger Airback in the center console. I know this was a problem for the 2004 TSX, but I can not find any reference to this in the 2007 TSX. The strange thing is I checked all of the fuses and they are okay. But every single backlight for the radio and climate control are no longer backlit at night. Does anyone have a wiring diagram that shows how these are powered. Even stranger still I picked up a replacement radio/climate and changed it out. THE BACKLIT still doesn't work. So it doesn't see like it is the card in the radio that is causing it.
Thanks.
