1997 suburban Brake lights and turn signals work but tail lights dont what do I do?

Brake lights and turn signals are on a separate circuit from the tail lights. Tail lights are on the same circuit with the dashboard lights. If the dashboard lights aren't working either, check the fuse. If they ARE working, check the headlight switch.


Why do your brake lights remain on when you have the lights on but work just fine when they are off?

This usually means a bad or wrong bulb in the tail lights


Your tail lights wont work when your headlights are on The brake lights dont work at all Fuses are fine Headlight switch is good What is wrong with your tail lights and brake lights?

I suspect either a faulty ground circuit, or a much easier fix, faulty bulb/bulbs. You might be surprised the havoc a grounded out bulb will cause an electrical system.


What is the problem when head lights are on and the tail lights dont work but the brake lights work?

If the headlights are on and brake lights work but not the tail lights, it is possible there is a short in the electrical wires. Another cause for this could be that the tail light bulbs are burned out. Most vehicles have more than one bulb inside the tail lights to control different lights at the same time.


What is wrong if the brake lights in a 1999 Cavalier Z24 do not work but the tail lights directional hazard and center brake lights all do and the tail lamps have been replaced?

The problem points to the directional/lights and hazard switch. The brake light wiring is part of that circuit.You can buy the switch after market it is about $70.00.


What is wrong when the dash lights do not come on also my tail lights don't work Fuses are all good flashers brake lights and turn signels work Just no tail lights or dash lights?

It is either a bad relay , cut wire or the wrong wattage bulb .


What if your brake lights work but not the tail lights?

Look for a fuse labeled TAIL LIGHTS. There are 2 separate circuits, one for brake turn and flasher and the other is for tail lights.


If your brake lights work but not the tail lights and its not the fuse?

Have you checked your bulbs ? The tail light / brake light bulb has 2 wires inside it In my case I have had to change each bulb because the brake light portion did not work but the tail light portion of the bulb did ( I'm assuming that your front park lights are working )


Why will both brake lights work when the tail lights aren't on but only one works when the tail lights are on?

may have the wrong type bulb check to make sure bulb has two contact points.
