The WD40 solutionI had the same problem on my 98 Grand Marquis. A Linclon Mercury mechanic told me the problem was most likely in the hazard flasher switch on top of the steering column. He recommended I spray WD 40 around the switch and push it down *and let it pop up several times and wiggle it around. It worked for me - problem solved. Apparently, over the years gunk finds it way in there, be it dirt, liquids, etc. Furthermore, he said there is no "flasher" you can replace as you may remember in older vehicles. Good luck. The rest or these posts are simply testimonials for the first answer
  • The WD-40 squirted in the emergency flasher switch worked in my 97 ford mustang. Thanks so much for the info.
  • Thanks for saving me the coins to pay a mechanic. I have a 97 Ford Van and the question fit my problem to the tee. The solution also fixed my problem.
  • My wife push the flasher and that started all the problems. I took your advise and it worked for me too on my 1995 Grand Marquis. Thanks for your imput.
  • I have a '99 Ford F-150 4.8 Liter V8, and this seems to have fixed the problem. It began as an intermittant problem and has gotten progressively worse over the past couple of months. I thought it was only affecting my turn signals, but I later discovered it also involved my brake lights. Moving the emergency flasher switch up and down a number of times solved the problem. Thank you!
  • This also worked for me I have a 1999 Ford Expedition. I moved the hazardous lights up and down and the problem was solved.
  • I thought I had checked the relevant fuses on my Ranger truck, but missed the one for brake-Emergency Flashers. My flashers were on - the button in the extended position when the fuse blew. Because the fuse went I didn't know the flasher was still in the on position. Therefore the turn signals and brake lights didn't work. It wasn't until I got the flasher in the off position that the turn signals started working again.
  • hey it worked for me too! i almost brought her in to the vultures till i found this. thanks!!!!
  • Worked on 1998 Lincon Continental...moved hazard warning switch in steering column up and down....worked great! THANKS!
  • The WD40 worked like a charm. I have been trying to fix this problem for 2 hours. I sprayed WD40 and problem solved. Thanks so much.
  • It works , don'ask me how , but it works.
  • Just used WD4O on the hazard switch of a 97 Aerostar whose blinkers have not worked for months. The switch now works freely, and the blinkers work, too.
  • I had a right front turn signal not working, sometimes. Then the left front stopped working, sometimes. Replaced lamps and still no joy. Tried the hazard flasher switch a few times and it started working but only sometimes. Sprayed WD40 into the hazard switch, exercised it a few times, and all OK now. Many thanks to the original poster.
  • Good Morning! Let me echo the repair of the WD40. I had the same symtems of turn signals, flashers not working. Checked all the fuses. Went to Auto Zone to seek advise, They called FORD for me (really nice guys here in Warren, Pa) Ford pointed them/me to a light processcor that costs in excess of $200. A dealer only part) Auto Zone then suggested for me to access the web and seek out like problems which I did. Thank you to the original poster of this issue and Auto Zone. Several squirts and I worked the switch...and presto...everything started working again! No cost at all to fix this prob. I already has the WD40!
  • It worked for me too on a 1997 Ford Thunderbird! Took me 2 days of checking things and not being able to use the care before I "Google'd" the problem. The internet is great and so is your web site! You should have an option for people to pay something if you site helped them. This was worth at least $50 (and more if I would have taken it somewhere).
  • Thank you VERY MUCH !!! The WD-40 solution worked GREAT !!!!!!!!!!!
  • Thank you, worked for my 1997 F-150!

Turn the emergency flashers on and make sure that they are flashing at a normal rate of speed. Then turn your emergency flashers off and try one of your turn signals and it should work.

If your turn signal flashers stopped working, play with the emergency flasher button on top of the steering column. Our 97 Sable turn signals quit once and luckily I pushed the emergency flasher button in and out many times and the signals have worked ever since. But the emergency flashers don't work, but I can live with that.

It has one flasher that controls both the turn signals and the emergency flashers. If the turn signals are working then the flasher is not your problem. However the flasher relay is located on the drivers side, under the dash, above the fuse block, mounted on the kick panel.

You need to check the fuse box, it everything is fine there. You have to test the relay.

You may have a relay problem your flashers and turn signal are on different relays or there could be a problem with the wiring in the steering column that goes to the turn signal

AnswerDefective emergency lights flasher relay.I had the same problem and I had to buy a new turn signal switch that you have to take off the steering wheel to get to it

Emergency flashers are a separate circuit. I would replace the turn signal flasher relay. To find it, switch on your turn signals and follow the sound. The flasher is probably worn. I hope this helps.AnswerWhat he said, or you have a bulb out...

My turn signals are not working on my 92 buick regal.

Hand signals are to this day a legal form of traffic control devices.

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

check the flasher itself and the switch

Answer---- On most cars there are two flashers. They are usually in or near your fusebox. Just use the process of elimination to determine which is which. One is for the turn signals and the other is for your emergency flashers. If your turn signals are not working, try your flashers. If they work, the problem is most likely the turn signal relay. Just put your finger on one and if you can't feel it clicking, it's most likely bad. They're usually round and silver in color and are light aluminum in composition.

You might just need a new flasher or a fuse.

you need to replace blinker can in your vehicle. the flashers and blinkers have separate flasher cans which is why your flashers still work but not your blinkers

I think there are two different flashers one for blinkers and one for the flashers.

The button that turns the flashers on is located on the steering column directly behind the steering wheel. It is located on the top or bottom right depending on model. The flashers themselves are your turn signals working in unision.

see if all fuses and flashers are intact.Check steering column connectors. +++ Also, generically, a possible faulty earth somewhere in the signal circuit.


"Pull off the roadway and activate your emergency flashers."

perhaps the flasher unit burned out or the switch is bad.

I am having the same problem. Do you have a new or old bodystyle? VW told me it is the 6th plug on the upper right side when you open the fuse box under the dash in drivers side. I changed it & nothing... when they thought I had a new bodystyle they told me it was in the steering column. I don't know & still need it fixed. Good Luck.

check the turn signal flasher unit itself, believe turn and emergency flasher are the same on the camery. good luck
