Ford F Pickup No Turn Signals - Ford Pickup Turn Signal Flasher Replace

In this video I outline the steps involved in replacing the turn signal flasher in F series pickups and other Ford vehicles. These models are similar in nature to this application:

I have a 1997 crown Victoria and it is so hard to find any videos of it being worked on so it’s nice to see this one being similar hope I can get my turn signals fixed

[@quepe7211]

I had this exact problem a while back. I was told that it was the turn signal switch. I had the complete turn signal switch replaced. I still had the problem. This sounds much more logical than replacing the switch because the lights would still work & flash for a second, but just wouldn't stay flashing until it was turned off. I'm about to check this out immediately. Thanks in advance if this is the solution to my problem. 👍

I replaced my turn signal flasher and the relay works and clicks but the turn signals don't light up on my dash nor on the outside of my truck. Bulbs are good. Short in the wiring? Are there fuses to check for the lights on the dash? Thanks.

[@javierorozco4193]

Thanks for the info on Flasher Relay. My 87 F150 has the "round" shape type inside the fuse box itself. The bad news is....I spent well over $100 replacing 1st the signal light Cam then the entire wire harness inside steering column. At the end of the day....new harness,flasher n working lights. Thanks Again Sir.

[@patriot1751]

Wow, I had to pull the dashboard off to get to it. After all these years (since 99’) it was good and stuck. Thanks for the info on where it’s located.

[@williampkubinski3696]

Good job, kept it simple

[@giseleSF1234]

I believe this is the cause of my erratic flashing turn signals that have now quit. No dashboard indicator and no lamp indication but all bulbs work for hazard lights. If you could share a steady/illuminated video of the location where the turn signal flasher came from, or a photo, that'd be awesome. And if you could show a steady video the panel retainers and share what is best to remove/pop them out, that'd be great, too. Regardless, this is sending me the right direction and I thank you.

[@giseleSF1234]

Oh, and your opinion if this part is reliable to replace with any compatible part from any auto shop, or if it is more reliable to buy OEM/Ford branded. I know with my Honda Civic, electrical parts (as I imagine this stuff is electrical - I'm not a mechanic and my knowledge has gapign holes) are best from the dealer for reliability. Huge difference in reliability and longevity. So huge, it could mean the difference between failing within a few weeks (aftermarket) or a few years (OEM).

[@texasdeeslinglead2401]

Thanks for posting this video. I've been hesitant to work on my turn signal issue as many videos state that the part is the main switch box on top of steering column. That's no cheap part. So it finally dawned on me that me hazards were in fact working. Back to KZbin I came . found this video , and lead me right to the twelve dollar offending part . thanks .

[@ThecardoctorTV]

Very nice!

[@boehmfarm4276]

I checked the fuse: its good, and I tried the flashing module and the lever on the column on our 2004 F-250 in my 2009 Ranger: those two are good. But still no turn signals. The emergency flashers work. Is there another fuse or relay not listed in the owners book?

[@bassjunkie2020]

Hum i have same issue on my 2001 f150 replaced everything only hazards work but no turn signal they quit for a month then started to work last week now there off again

[@GrouseHiker]

I hate to be a spoil sport, but i just replaced my 2000 F150 flasher without all the disassembly. F250 may be more crowded. A little hand strength is needed (little is all have left at my age), but there was plenty of room on mine to pull the cover off.

[@olallaeddy]

Had my truck at ford all day and I have the new relay and they said its in the fuse box and i have the wrong one.. Mine will flash a couple times then stop so im sure Its like your video. Hope I can get my hand in their.

[@kenwhitney9146]

My flashers quit intermittently, my cruise control quit, my horn quit all at the same time or close. Any ideas there. Your video is a good one btw!

[@urieldelteco]

Ken Whitney you might have a bad clock spring. Symptoms would include buttons on the rotating side of the wheel not working, as well as after an airbag light on due to a loss of contact with the airbag that also also on the rotating portion of the wheel

Hi there... I've got a 2001 Ford F-150 Lariat supercrew with signal mirrors and cannot seam to find enough info on them. Would there happen to be a fuse for the signal mirrors? If so, which panel would you think I need to look at? Thanks in advance...

I have an 89 ford f150...the hazards work and the fuse is good but I don't have signal lights. There is no sound when switch is put in direction of turn. They did work when I bought the trunk a week ago. Any ideas? Would it be the same thing replaced that is in this video? And is it in a different location in the older model ford? I did find a round flasher plug on or in the fuse box under dash. Is that it? I'm so new to learning how to fix and repair my own vehicle due to not being able to afford high mechanic fees...so I'm teaching myself how to do the easy fixes. Any suggestions would be greatly appreciated..it's hard to find any how too's on this older style truck.

I used your video to find my relay and replace it, and made my own video. I gave you a shout out, and am placing a link to your video in the description on mine. Thanks for showing us where that little booger is at, but you didn't say how to get it out! I reached up under the dash around the heater vent. You have a better way?

[@misterbulger]

When I turned my hazards on one day, my turn signals completely stopped working. I blew a tail light (already replaced the bulb) and now I notice that my front left hazard light doesnt blink either. But the rest of the bulbs flash with the hazards turned on. But when I turn on my headlights, that corner light seems to light up. But with the arrow indicators on the dash, only the right arrow flashes with the hazards on instead of both. (1991 E350). I pulled the bulb out and the filaments seem to be fine. Should I try to replace the flasher next? I briefly heard a ticking sound coming from next to the battery. There are a few relays in there... not sure which one is ticking or which number relay controls what. The ticking stopped after a few seconds and it won't do it again.

I also learned how to install a fuel filter, tensioner pulley, all lights, oil filter, spark plugs and wires, brake pads and fuses. I'm never going to mechanic unless I have serious complications.

[@2lotsill]

I’m here because of a constant clicking/ buzzing sound with engine OFF key OUT. Sounds like a Geiger device, the ones that detect radiation. Isolated the noise to the switch under the dash. No issues with turn signals, don’t think the relay is the problem, think the issue is with the Hazard flashing switch on steering column. 2004 F250 power stroke
