Hello all. I have a 2003 Grand Prix GT. The car has an automatic headlight and taillight system. For some reason they are no longer automatic. I had to turn my headlights on manually and neither tail light comes on when I do this. The tail light only comes on when I brake. Also my car has a sensor on the dash so when it gets too dark the lights on my dash turn on..and that no longer happens. Could this issue come down to a fuse? I need help asap!! Thanks in advance.
