Recently bought a 1996 Chevy Silverado 1500 truck and noticed brake lights/turn signals are not working. Replaced brake light switch and then the turn signal switch neither one is working. What should I check next????
The bulbs. The brake light bulb and turn signal bulb are the same. Check for good ground and then for battery voltage at the socket. If no battery voltage is seen, check the fuses and relay. If they check OK, trace the wiring to and from the brake switch and repair as needed. I will supply you with a brake light wiring diagram to help you trace the wiring.
