In that case the only things left to test are the grounding and the bulb connector. Make sure the connections are clean of corrosion and tightly secured.

I have 89 bronco 2 my brake lights turn signals both work my tail lights don't work have check fuse n blubs what might be the problem


The turn signals and brake lights use the same circuit and filament in the bulbs. The tail lights are on the other circuit which comes from the headlight switch.
Do you have power on the tail light fuse ?

1994 Chevy C1500 truck. No rear brake lights


Most likely this is a brake light switch issue. Replace switch.

If your emergency flashers don't work, all flasher bulbs are fine, but flashing too fast, then check and replace Hazard light switch.

Running lights work but no blinkers or brake lights. Changed fuses and bulbs no luck


I'm inclined to believe it is the turn signal switch. When you select left or right, the brake light is removed from that side, and the flasher is connected to the bulb instead, making the brake light on that side flash as the indication that you plan to turn. You have lost everything, but the simple answers check out.

If you have lost signals, brake lights and tail lights, then it is more likely that the ground supplied to the bulbs is not working, since the tail lights share noting in common with the brakes lights and turn signals but ground.

If the tail lights work, the fact that the brake lights and rear turn signals share that switch starts to look meaningful — even more so if the front turn signals also don't work. But the front signals and the rear signals use different circuitry in the switch, so it would be something more mechanical in the switch than electrical in that case.

Rear turn signals and brake lights out. Front signals and rear tail lights work fine.


the brake lights and the rear turn signals should be the same bulb check the bulbs to make sure they are not blown does your third brake light work if all brake light are out and the bulbs are good check the brake light switch on the brake pedal
