Rep Power: 0

I have a 1991 Civic CX Hatchback. I keep blowing the main light relay under the good. No headlights, taillights, park lights or dashlights but still manage to have brake lights. The lights are still factory, no upgrades. On top of it wipers dont work either. Anyone know where the best place to look or any possible common issues that might cause this. i dont know much about troubleshooting electrical and i cant afford a shop to do it. Any help would be appreciated

Start by checking the grounds. Then check the wires/connectors starting at the headlights.
