No break lights, blinkers or hazzards. I changed the fuses. That wasn't it. Still No breaks, blinkers or hazards. Where is the relay?

How do I know if my flasher relay is bad?

Symptom of a bad or failing turn signal / hazard flasher is hazards or turn signal lights that do not function. If the flasher breaks or has any internal issues it can cause the lights to malfunction, or not respond at all when the turn signal lever or hazard light button are pressed.

Symptoms of a Bad or Failing Hazard / Turn Signal Flasher - YourMechanic

For the cost involved, I would change it.

Follow the flasher wiring to fuse box and locate the fusible link. Looks just like the wire but softer exterior and it's a fuse able wire that can break down. Should be along the driver fender under hood.

remove hazzard switch from dash, and unplug wires from switch, keep wires from touching each other w/ tape. blinkers should work. change out hazzard switch w/ new switch.

check to see if you have a light bulb out if one is out it will blink faster

I am unaware of what a "CO" display is.
Now with the blinkers, hazard, horn and brake lights not working that may be the multi funtion switch (blinker switch) that is located inside the column (where the blinker lever attaches).
Obviously the blinker, hazard and horn will all work off of something in the column. Brake lights, you may think a switch on the pedal.

the brake lights do work with that switch but when you have the kind of tail lights where a turn signal light shares the same bulb as a brake light, the brake light is cancelled for the turn signal by running through the multi function switch inside the column.
The third brake light does not blink so its not on that same circuit.

I would also look at the blinker relay.It's a combination blinker/hazard relay.It's up under the dash on the left of the steering column.Hope this helps

maybe the blinker or flasher is defective or one the bulbs is defective or open

Hi mate this is an easy wiring diagram to use and you only have one flasher unit for both flasher and Hazard operations. Sorry for taking so long to answer bit buzzy. I have a circuit stored some where in my brain for a two flasher unit also but this one is the most simplest you will get.

Remember to fuse the Ignition wire. Ask the supplier which contacts are negative and positive on the flasher, don't mix them up you will blow up the flasher. If the dash lights aint working run a wire parrallel to those wires from the circuits left and right (two terminal Type). Some flashers have a build in (three terminal Type) dash signal terminal.

check the fuse and relay that control the blinkers, also check all bulbs make sure they are good

Check the multi function switch (turn signal/hazard) . Dirt gets in the contacts and causes your concern.Replace the multi function switch.
