I dont know which light your talking about. The only light on the tail gate is the license plate light, which comes on with the parking/head lights. The next closest light is the cargo bay light, which has its own switch on the dash, and comes on with the park/head lights as well.


Wait...do you mean the tail gate indicator light in the dash? If so, it shouldnt come on just because the top is off. It comes on if the tail gate is not shut all the way. Take the tail gate down, and shut it a few times to see if it goes out. If not, you probably have a bad switch.
