First go near the battery and look for a single wire connector with a white/blue wire. This will not be plugged into anything but we do need to make sure it is not damaged. Next locate the driver side rear heelboard fuse box to check to make sure there is no corrosion there as well. It is located behind the carpet cover in between the rear seat cushion and floor. Remove fuse #14 (10 amp) and see if the lights go out.
