possible cause for all rear running lights to suddenly cease to light up even though the bulbs and fuses are not burned out
4 Answers
If the bulbs and fuses are good maybe the wires were damaged. I would also check the light bulb connections for corrosion.
is there power to the rear assemblies..pull one and check...do you have brake lights when you press the brakes!?!? bulk head connector.. turn signal switch/head light switch..ground issue.
A defective turn signal lever (multifunction switch) can cause erratic operation of the turn signals and other exterior lights. Depending on the fault
do you have inside turn signal lights on dash>> more in if you can..if you have not found the problem
