Changed flasher bulb, replaced 5 amp fuse, replaced relay - I even sacrificed my wrist which got stuck inside the frame of the light casing, and took me 15 minutes to reclaim use of my arm. Anyway, it still doesn't flash front/left turn signal. All others lamps & signals are fine. I guess 3 out of 4 aint bad! :)

How did you solve your issue ?
Tooty from United States 3 years ago
Fixed it by buying new set of light assembly. The whole thing, which includes the headlights. Bamm, perfect.

Can anyone tell me where i can find the relay forthe turn signals. I installed LED bulbs and now they flash normal on the outside of the truck, however, in the truck they are flashing fast. i was told i could replace the flasher relay with an EP27 or install a resistor.

Hazards/turn signals not working

Ford F-150 1998 F150 190000 miles
I can't get my hazards or turn signals to work. I've replaced the flasher relay under the dash and the 20 amp fuse is still good. All the blind are good. Still doesn't work. So now I'm looking at the turn signal/flasher switch on the steering column. Has anyone ever heard of one going bad? It's over 90$, so I wanna be sure. I've haven't blown a fuse yet for this.

Yes, indeed, I've heard (and read) of many people that had this problem and it got fixed after changing the flasher module. You should be able to get one for less than 20 bucks. I hope it fixes your problem as well! Let me know if it does, so that I can count one more on the list ;)

I’ve replace relay , checked fuse, still no turn signals. They work time to time. Any suggestions

I had a weird situation where the right turn signal to a trailer hooked to my 2003 F150 would not work. I found it was a bad small fuse in the plastic fuse cabinet under the hood. That cabinet is a bear to open, but it swings up pulling from the fire wall side of the truck. Feel to the left rear corner as you look at it. A mirror was helpful to see what I had to pull. Inside at the top was a fuse creamish/clearish in color with the number 2 on it. Replaced it. Right turn signal works. Go figure, but that was the problem. I would note my left turn signal on the trailer worked fine.

Check the individual bulbs. If all good, you probably need a new flasher unit.

Brake lights and turn signals

Ford F-150 2012  165000 miles
Ok have a 2012 Ford F150 XLT brake lights and turn signals do not come on. I have replaced the turn signal relays, the multifunction switch, the brake pedal switch, several fuses that were not. Blown but replaced anyways, the bulb socket housing, as well as wiring for brake lights, after this did not work I changed the PCM relay out and replaced it, put brand new bulbs in, and also had a mechanic do a reset on the computer but still have no signal lights and no brake lights. I am completely stumped now as I have changed everything possible that could go to brake lights and signals lights and s… Read complete

Yeah ive replaced everything and cleaned all ground connections. Still not working and now the license plate lights and taillights are out and just the same all fuses and relays operational. Oddly enough I hooked my old trailer up and plugged it in and for about one block I had right turn blinker , the left blinker on solid and brake lights. Then nothin
Shanda fay from United States a year ago
I have a 2012 F150 with similar issues but replaced the bulbs and now have brake lights and turn signals but still have no license plate lights does anyone know what fuse powers these lights or what fuse it is grouped with? In the meantime I guess I will tape a flashlight to the bumper to illuminate the license plate when driving at night … hoping it’s not a wiring or electrical issue as I am not at all handy with auto mechanical issues if it is beyond a bulb or a fuse replacement or something very basic!

2001 f150 rwd Lariat with no turn, brake, reverse or hazards but have tail lights. Any suggestions?
Been there done that from United States 2 years ago
You are likely dealing with a blown fused link. A fused link is not a fuse,but a solder joint somewhere in the main harness. When a fused link gets overloaded,the solder joint is designed to melt out,thus breaking the connection so you're ride doesn't totally burn up. Since they are not readily visible,they can be time consuming to find. But when you do find it, just replace that section of wiring and it should fix your problem

Kinda the same except it was my wipers instead of turn signals. I replaced the relay under the dash for the blower motor and seems to have solved all of the problems with heat ac and wipers. Dont know if thst is your problem but mine was similar.

Fuses, a broken wire, bad window motor for the age it has im sure the motor is burnt. As for turn signals check fuses, check bulbs, and if it has the emergencies button on top of the steering wheel sometimes the sun can brittle the contacts inside i repaired one by applying a shim to give it pressure.

Left Turn signal flashes really fast... But right side works normally

All left turn signal lights are working but when I use the Lsignal it hyperflashes. At first it was intermittent... but now it does it all the time... I disconnected the battery thinking it would reset what ever was causing this issue... But it is still doing it.

Lol. Yes I had sane oroblem. First find out where your dead short is on your trailer. You must have switched the ground and power lines on the trailer wiring. Or you have one of the electric brakes wires grounded out before load. The wire your looking for is your brake output wire. Its on the bottom of your plug. Ford has it printed on plug cover. Your fuses are under hood drivers side in fender well. I think they are 10 amp and are #19 and 20. Very top of box toward head light. Also disconnect battery and pull air cleaner look for wiring loom coming from back of truck. Unplug connector clean brake pin on plug it will be discolored from dead short and clean. Reconnect. If you still don't have power check connections in module connected to frame I believe it's the abs module. That should get your lights abd brake power out wiring working. It took me a couple of hrs to figure this one out. Don't give up. Lol

Same problem in my 2010 5.4 lariat. Haven't had right signal for awhile now.every now and then it will work for a day or so then nothing. I have changed everything just like you did even the pigtails still nothing. Dealership says that the smart junction box must be replaced. That's $1,000 bill just for right side signals.

Dash lights go out when I turn on headlights, blinkers too.

Ford F-150 2005 4.6l 160000 miles
If I turn my headlights on the dash lights go out and the blinkers won't blink. Sometimes it won't start, either. Wiggled the steering wheel one time and it started right up. Mostly didn't start in park then would start in neutral. Now, neutral starts are not always working.
