Q: No lights or start after changing brake booster and switch on a 97 Silverado.
I replaced brake booster, I noticed brake lights not working I took off and inspected the brake light switch. Now it won't start or even try, the headlights do not work, the hazards make a constant vibrating sound. The fuses are good, bulbs are good, I'm sure it's a wiring issue but I cant figure it out. The inside dome lights work and wiggling stuff sometimes gives the door open sound. It was working before I messed with the brake switch. I tried pushing together every wiring connection I could. Need help badly.
