   I am having issues with the fuse box under the hood. I keep shorting out on my headlights ans AC clutch relay. I've purchased new head lights (bulbs), replaced them and they still didn't work. I checked the fuses after investigation online and they have blown. I had my AC completely fixed and it ran fine for a while, then stopped working. I had it checked and was told the AC relay clutch fuse was loose. I replaced it. Three weeks later it shorted out, again.
