High Beams and Low Beams not operating or is it just one or the other?

Start with inpecting your bulbs and fuses. Let me know if they are OK. If not, replace necessary fuse or bulb.

I replaced the head lamps and the still dont work I think it might be a relay but I dont know where they are under the hood.

There is no headlight relay. There is a headlight circuit breaker located in the headlight switch itself. Replacing the headlight switch should solve your troubles.
