I bought a used 02 Nissan Frontier with 200k miles on it. The temp gauge does not work, the fuel gauge only register half and the SRS air bag light not showing. I bought a used instrument cluster, same model. Now all gauges work. The air bag light is flashing. The only modification I can see is that the previous owner installed a SONY blue tooth radio. I tried three separate instructions how to reset air bag here at club frontier but nothing work. It will only go to diagnostic mode. One steady light pause followed by three flashes/blink. I've checked the center console above the radio to make sure the switch and light connectors are plugged in, and they are. Any help or suggestions greatly appreciated.
