My 2002 BX23 has issues with the lights. Neither the tail lights, turn signals, nor the hazard flashers are working. THe headlights have been wonky, especially after getting wet, but I have replaced the switch and the problem appears to be solved. As for the taillights, I have gone through several iterations of trouble shooting this. I have verified that the fuses are good, and there is power through the both the turn signal and hazard switches. I have not been able to flasher to see if that is the problem. But since the tail lights are independent of the turn signal and flasher, I am leaning toward a ground problem. Any suggestions on locating the flasher?
