Hope helps.

radio may have been wired improperly or fuse may have blown. First check fuses. Below is the color scheme for your radio wiring. The dimmer wire is White with a green stripe. This wire should be connected to the orange wire of your aftermarket stereo. If you have an unusual stereo, leave the factory wire unhooked (and insulated) until you can verify which wire on your stereo is for the light. Let me knoiw if you have questions.
