ok so mt tailights arent working and i think ive tried everything. i cleaned off the ground to make sure that there was no build-up interupting. that didnt work. i replaced the bulbs(all of them) that didnt work.i took the dash off and seen if anything was loose. the only thing i found was an adapter that goes into the gauges. i plugged that it but still no tailights. the brake, reverse and turn signals work just not the tailights. i replaced the fuses with the fuse that "glows when it blows" and once i put it in and turned on the lights it blew. which im guessing theres a short somewhere i jsut cant find it. im clueless now. for the fuel gauge it goes up then goes right back down once you start the car fully. im guessing it isnt a wire, possible the float in the tank. im not sure. any help will be greatly appreciated.
