Brake lights out; bulb, fuse okay

LED replacement bulbs are nothing but trouble on a vehicle that didn't have them as OEM equipment. In most 'modern' cars, the flashers are controlled by a signal from the Body Control Module or Combined Power Modules via a relay. You need an auto electrician or if the Parts Store sold you the LED bulbs and flasher relay, go back and ask them to sell you the right items to make it flash correctly.

Check the wiring from the signal stalk

Do you have brake and parkng lights? The turnsignal switch on the column is just designed to relay a path to the flasher and then it is designed to interupt the brake and some of the parking lights lights, which cause the flashing on and off. Double check fuses double check bulb socks and bulbs for good contacts. Does the 4 ways work? If the lights all flash then locate the turn signal flasher and switch with emergency flasher if possible to rule out relay. If those are all good and the emergency flasher lights work and bulbs, then you would have a problem with the turn signal switch. Hope this all helps

Check for power and ground to the lamps. Most likely you have lost ground, since you replaced everything else.

there is a short in your liting system

Check your fuses of course,you probably did.Listen your not going to believe this,the wire at the brake light switch can be bad.sometines the wire can break inside the vinyl cover just a milameter.use a test light for presence of voltage at the switch and check a few inches back to see it voltage is present. MAKE SURE YOU HAVE VOLTAGE AT THE SWITCH!

Sounds like the flasher unit to me. Normally the emergency flasher and turn signal are separate.

yes it is flashing very fast on one side then you have a bulb out. Turn the turn signals on the side flashing fast and look if its front or back.

I would check the bulbs, first with just parking lights on - making sure all light - then to see if brake lights work.

If brake lights work, check you parking/signal lights, as they may be of the "two filament" variety. If this is the case, and they are not burned out, check to make sure that the FLASHER module works and that the button for the EMER FLASHER works.

If either is not working, neither will your turn signals, as they depend on the flasher module.

Good luck !!

Hi,

If I understand you right based on your post/description, the signal lights would still turn on even if any or both of the flasher relays are removed. Should this be the case, then the signal lights are not getting the power from the flasher relays but from the brake light circuit.

Perhaps your concern is not with any of the flasher, but simply missing or loose ground more particularly with the rear lights. Perhaps you could try determining which of the wires for the brake lights and signal lights (as they come out of the light assembly) would be ground . A test and even possibly a temporary workaround is to hard wire a second ground connection from the determined ground wire of the lights and attach it to any conveniently located bolt or screw to the body. it may be to your advantage to do this on all the rear lights assembly.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
