One problem related to dash wiring has been reported for the 2004 Mazda RX8. The most recently reported issues are listed below.
I bought the 2004 Rx8 used. It only had 16,000 miles but the previous owner had broke the rear defrost button and the dealer sent me a new one in the mail. I have remover a million interiors and stereos before so I was doing it myself. In order to put the new controls in you have to slide out the entire face plate which connects to the radio, cd player, and air controls. Once I put it back in and hooked everything back correctly, it would not work. I have removed it several times and the entire control panel does not work. All the prongs are good the fuses in the car are all good but it still doesn't work. The blower motor, the ashtray light and the seat warmers all work but the screen that displays the time of day, the outside temp and all the radio and air equipment still doesn't light up. I just wonder if the radio has gone into anti-theft mode and shut down. I used to own an Acura and it came with a code to punch in if your radio ever shut down. I just want it fixed. Any suggestions??.
