I have a grand vitara 03 my rear lights have
stopped working I've changed all the bulbs but still
nothing, would i be right in turning to the fuses for
this or is there something else I need look at
Fuses are next only because they're easy, if all the lights are out I would look for a rear wiring harness plug in disconnected or a bad ground wire. Did you use the correct bulbs?
I didn't notice you specifically said brake lights, after fuses check brake light switch then harness connectors
Brake light switch . Inside up on brake pedal. Check for proper alignment then if no joy R&R the switch. Easy repair.
