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 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!

Where is the turn signal flasher on a 1996 Chevy Caprice?

Mounted on auxiliary fuse block under the driver side dashboard, above the left side of the brake pedal. There are two flashers at the top of the fuse block. The one on the right is for the turn signals, and the one on the left is for the emergency flashers. Just pull towards the rear of the car to remove either. You can test for function by swapping one flasher for the other, or temporarily regain turn signal use by swapping in the working emergency flasher.

Sounds like an electrical problem, check your battery, alternator, and fuse box, and light wiring.

Left turn signal won't work with headlights on what causes this?

I could not be sure about your particular problem, but I had to replace the Multi-Function and Turn signal switches in a 96 Lumina for similar strange problems of Brakes and signals not working in particular scenarios.

What's the problem when your blinkers stop working and it's not the fuse?

You probably have a bad flasher. This is the thing that actually interrupts the blinker signal, making the lights go on and off. It's location will vary by make and model of vehicle, but is usually under the dash, or in the steering column shroud. You can find out about the flashers in your car by checking in a Haynes or Chilton manual, or by running by a dealership and asking them where it is.

What is a quick fix if the turn-signals stop working on a Mercury Sable?

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.

Where is the emergency flasher located in a 1992 Honda Accord?

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.
