Whenever i break the light is suppose to come one, but now its out. What do I need to replace???

 

Same problem as me I diagnosed it as a broken resistor on the LED board. Now I need to find someone who knows what the value of that resistor should be. First though, make sure you have power back there (need voltmeter)

 

where can you check if theres power going to the spoiler light?

 

The connector in the trunk behind the trunk carpet lining.
