Why would the turn signals and hazard flashers on a 2001 Lumina all fail at the same time?

Because the hazard/turn signal relay has failed. A defective/intermittent turn signal switch can also cause this symptom.

hazards and turn signals have separate flashers. replace flasher for turn signals

Flasher relay bad. This is a separate flasher relay from the one controlling the hazard lights.

User Avatar

It has 2 different flashers. One for the turn signals and one for the emergency flashers.

The first thing I would check is your 'flashers'. Most vehicles come equipped with two: one for the hazard lights and one for the turn signals. Flashers are usually round, but come in various shapes. Normally located in your fuse panel.

because of the flashers relay in dash board.

I would start with changing the flasher in your fusebox. It's the round looking object in one cornor of the panel. I have all ready changed the flashers and the fuses what can I do now

User Avatar

either a bulb or the signal flasher relay located on the fuse panel usually opposite the hazard flasher relay

User Avatar

There is usually a relay for the flashers and turn signals. It is usually a round metal looking thing in the fuse box. This is usually the norm. I have never worked on this specific vehicle, but they are all simular. Good luck.Brad.

turn signals and emerg flashers work off a flasher can. go to any auto store and buy a new one they are cheap and easy to replace

User Avatar

The emergency flashers and the signal lights are separate systems. Each has it's own fuse, switch and flasher relay. If your turn signals light up but don't blink I would blame the signal flasher relay.

User Avatar

We need more information. Never work? Come on and not blink? Do the 4way flashers work?

User Avatar

The bulb is bad. Turn signals and flashers use different bulbs.

User Avatar

turn signals and 4 way flashers are on different systems and use different flashers You would want to look for the turn signal relay, try putting on your 4-way hazard flashers so you can here the clicking noise of the relay, they might be under your dash. In my car it was underneath the dash directly in line with the steering column, above the brake pedal.

I hope you are not driving this vehicle with so many faults? Obviously an electrical system problem. Start with the obvious thing, fuses, then check all the bulbs by removing them and looking at the filament wires and the base to see if they are broken or corroded. Finally check the flasher both regular signals plus the hazard flashers, and replace as needed.

User Avatar

Try replacing the hazard flasher. If that does not work, double-check to see that you have the proper bulbs and fuses installed for the brake lamp circuit.

The module in the dash is for the turn signals and hazard flashers. It is the flasher unit for both so since this occurs when using either system i suspect the module itself is faulty..it is a common part that fails on these.

I just checked my '97 Sable wagon for a related problem; (HAZARD LIGHTS DO NOT FLASH but my Turn Signals do). I checked the HAZARD FUSE (15 amp), it was fine; I got my hand under/behind the dash and wiggled all the wiring harnesses and harness sockets I could feel, then all of a sudden my flashers started working. Trying to isolate it I pinpointed the problem to the HAZARD SWITCH located above the steering column cover, (PUSH-ON, PUSH-OFF) and wiggled the switch and then they stopped again, and/or started to work again. It is probably a loose connector which will require a total dismantling to get to it. BTW: The Turn Signals and the Hazard Flashers work from the same RELAY, a Blue Ford Relay located under/behind the dash, to the left of the steering wheel. This RELAY is replaceable with a UNIVERSAL FLASHER RELAY from any auto parts. In your case, I would check the Turn Signal FUSE, it that is ok, then substitute the Turn Signal RELAY with another.

4 way flashers and turn signals both have a "flasher can" in the system to make the lights flash the turn signal and 4 way flashers are controlled independantly of each other try replacing the flasher can for the 4 way flashers it is obvious that the bulbs are ok because they work on turn signals

User Avatar

Check the connections behind the dash (Dimmer, clock, hazard, and cigarette lighter) but specifically the hazard lights. If this connection is not made well then it will affect the turn signal. I would also check to see if the running lights come on. If they don't then I do not this this solution will work.

User Avatar

for hazard fuses check all the bulbs in all the turn signals/running lights. Next check for flashers, they are usually located with the relays on the vehicle, and on fords are typically round cylindrical thing that is about the size of a quarter If you are having trouble finding them turn on your turn signals and listen around your relays for something clicking with the lights. http://grote.com/product.php?product_number=44310 one trick i have learned is that you can swap the flashers around if there are more than one, and if that makes your hazards work but one of your blinkers not work then you know you just need one of them. they are cheap and do go out relatively often. if nothing else works i would check wiring harnesses and the hazard switch. hope my long winded answer can help.

Yes. The relay that controls the turn signals is built in the switch.
