SOURCE: hazards and blinkers not working

There are separate fuses for the turn signals and blinkers, but you should check both of them just to see if they're good.

You may have a burnt out turn signal bulb as well. I know that this sounds like an obvious answer, but a single bulb can sometimes disable the entire system because of the way that some flashers operate.

You could also have a defective turn signal/hazard light flasher. This is located under the dash board on the driver's side between the steering column and the door. You have to remove the sound insulation/kick panel (the cover on the bottom of the dash board) to reach the flasher (it is easy to remove - I don't think you even need tools).

Hi Bill,I think before replacing anything else you should give that hazard switch a good workout.The switch doesn't get get used very often and the contacts get corroded and can upset the indicators.Good Luck.

Hazards when engine starts.replaced flasher unit to fix blinkers.where is the electrical interaction point between the blinkers and the hazards how do you fix the blinkers on 1996 plymouth voyager?

Traditionally the hazard switch is where the direction indicators are switched from the indicator stalk switch and ignition switched supply to battery supplied hazard lights. By 1996 these functions were rapidly being computerised so taking things for granted is definitely unwise.

I strongly suggest you obtain a wiring diagram before getting too involved...

Indicater or flasher problem on jeep cherokee 2003

If your having problems with your indicater or flashers on your vehicle then their are a couple of things that would be causing you problems.Now if when you press left or right turn the light flashes fast when turning one way but not the other then this indicates you have a blown bulb on the side that is causing it to flash faster so you need to press it to that side and have a look at the front and back bulbs and change the one thats not working.

If on the other hand your flasher/indicater works sometimes and not others then this is usually down to the flasher relay located in fuse box (see pictures below)
To find out if it is the relay and not the flasher control that you press to turn the indicator lights on is to try using the hazard warning light button press this and if this works every time then the chances are its the control and not the relay (see pictures below) but if it sometimes works and sometimes dont or if it dont work at all then this points towards the relay so changing this should then solve your problem

Why does turn signal sound all the time unless the br(ake) is pressed?

Taryn, sounds like a faulty turn signal switch, or multi function switch is defective. Check all the bulbs and sockets first for damage wires, burnt wires or bulb socket, cheapest part to change besides bulbs would be the signal flasher or the signal relay if you want to go this route. Below are trouble shooting links you can read or watch.

Hazards dont work but blinkers do

Blinkers and hazards normally work on the same fuse. Sounds like the hazard switch has a problem.Get the hazard switch out and bridge the two connector wires to the switch. If the hazards then work the problem is in the switch.If it don't work you may have a problem in the wiring between the switch and the flasher relay.

I have a 1990 Mercury Cougar. Several problems...Blinkers, hazards, horn, and break lights are not working. However the break light in the back window comes on when the break is pressed. Checked fused and...

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.

2001 jeep grand cherokee laredo, lights come one intermittently, horn came on unexpectedly and wouldn't turn off. How do I fix that?

Lights intermittent can be caused by switch or relay. Try swapping the Low Beam relay with another similar relay (horn relay is a good choice) to see if that resolves it. These relays are in the Junction Block--may be under the hood or in the car but not in the big box by the battery). If this doesn't fix it, the problem is likely the headlamp switch.

Horn coming on is usually caused by a broken switch or stripped wire insulation inside the steering column. You would usually have to take the steering wheel off to fix it, and this requires special tools; however, if the problem happens to be under the steering column shroud, you may be able to fix it without taking off the steering wheel. Take the shroud off and see if you can follow the black/red horn wire. Follow it as far as you can to check for stripped insulation contact with any metal. If you lights switch is bad, you can also change that while you have the shroud off.

Please let me know if you have questions.

I have no brake lights, the blinkers run really fast and if the headlights are on the blinkers will not run at all while braking. Any ideas?

Have the multi-function switch and its circuits tested. The multi function switch is the blinker arm and the components its attached to in the steering wheel column. The multifunction switch has to do with blinkers, cruise control, wipers, wiper spray, high beams and also tied in with headlight dimmers/daytime running lights(if applicable) and hazards usually.

A good place to start.
