so my head lights are not working the switch works but no head lights

To locate the under hood fuse box, follow the positive cable from the battery. It may lead under the battery. But do yourself a favor first and check the voltage at the headlight with the switch on. The older rectangle bulbs go out on hard bumps. I've seen it more than a couple times. If you have no power at the headlights (use a test light or DVOM), then check all the fuses. I know it's backwards, but it is pretty likely just bulbs.
