I have a short in my headlight wiring that causes the lights to flash and flicker when the car is off. I don't have time to repair a the moment so what fuse and where is it located to stop power to the lights when not in car? Thanks

Hello, I will attach the diagrams for both the fuse box under the hood and the fuse box under the dash on the driver's side. Seems like F9 under the hood will turn off junction box inside the car.

Where is that fuse box? I've searched under dash and all I found was the security box. Also, that mentions every light except the headlamps or high/low. Does that seem possible?

Hello, the SJB is under the dash on the driver's side. Likely behind the driver door, there should be a small panel in the instrument cluster to take off. However, if you pull F19 under the hood it will disable the SJB and therefore keep the lights turned off. This should be a 40 amp green fuse. Yes, there is not a dedicated fuse for just the headlights. I will attach a wiring diagram.

Behind the drivers door? Do you mean where the dashboard meets up with the door when closed? I've looked all over and can't find it. What's does s stand for in sjb? ? Junction box? Thanks

Hello, SJB stands for Smart Junction Box. It is located under the dash on the driver's side. It will be found right next to / in front of the emergency brake pedal. There should be a cover to remove to access those fuses.
