My ford explorer lights and dash lights stop working only the headlights work I checked all of the fuses already what else can I do?

Check the ignition switch for wear, pitting, or melting. It likely needs replacing.

What do u know about the relays do u think that could possibly be the problem

Very unlikely.

Be sure to disconnect the negative battery cable first.

U know my dad told me it can also be the light switch u nowhere u turn on the lights what do u think?

I doubt it, if none of the lights on the dashboard light up.

Did you check out the ignition switch?
