No brake lights, turn signals, or hazards

bazelightyear · 01-23-2013, 11:26 PM

Any ideas? I checked the fuses and they're all fine. When I try to turn on the blinkers there is nothing whatsoever. No light on the cluster, no clicky noise, nothing. Same with the hazards. The only brake light that works is the 3rd brake light. Is there a relay that controls all of these things together? And where would it be? I'm pretty sure the hazards and signals are related, but would the brake lights be a seperate issue? Any help is greatly appreciated. It's a 2003 svt by the way.

Could be the Hazard switch, all the turn signals go through that. I've had problems in the past with mine and it ended up being the hazard switch.

Thanks for the quick response. Would the hazard switch have anything to do with my brake light issue?

Maybe, it goes through that switch so I imagine that would be the problem since the turns don't work. I hope it fixes it, electrical problems can be a nightmare.

Yes, brake lights go through the hazard too. If your rear tail lights, the ones that come on with the headlights (parking lights), are coming on, but not the brakes or turns, then that's likely to be your problem. If the tail lights are not coming on, then you are more likely to have a grounding problem.

You can check to see if the switch is still plugged in tight. Remove one of the two center dash a/c vents and you can reach inside and push the connector on the back of the switch. This is a pic with the center console removed. This is not needed just to check the connection.

Thanks a lot for the help guys. I checked the connection and it's fine. I'm gonna try to pick up a new switch today and I'll let you know if that does the trick.

So I replaced the hazard switch and even the turn signal stalk, and still nothing. I'm completely stumped. Fuses are good, wires are good, connections are good, grounds are good... Is there any possibility that there's an issue with the bcm?

Check the wires coming out of the body and into the hatch, those are known to get split from opening and closing the hatch and grounding out causing all sorts of weird problems. You'll have to pull the black boot back to see.
