The trunk mounted third brake lights doesn't light up[!], but the brake taillights assembly lights up when the brake pedal is pressed. The bulbs are fine, it seems like there's not enough power going into the lighting assembly. I checked the fuse box in the engine compartment and the one small one in the trunk and they are all ok. Don't feel like taking the car to the dealer for a small thing like this and I don't really trust them. Is there any other fuse/fuse box that is somewhere hidden in the car? Any help is greatly appreciated.
