Signal lights stopped working

Check the wiring from the signal stalk

Brake lights run through the hazzard switch. There are known problems with this, and the multifunction switch. You may need to buy a new hazzard switch and OR the multifunction switch. Before you do that, check the pigtail that goes into the brake switch up by the fender, make sure it's not shorting out up there. Happened to me!

The flasher may have gone bad for the turn signal, and there may be a second flasher for the emergency flasher lights. Look and listen for a click of the flasher for the emergency flasher lights. Then, the other flasher is the one to replace.

Good luck on this repair.

The flasher relay is mounted in the main fuse panel under the dash, driver's side.Are the lights coming on at all, or is there nothing ? it is possible that you may have a bad ground wire to the signals. Do the emergency hazards work ( lighting up and flashing?)If so, then your ground is good and it could very well be the flasher. You should be able to switch the emergency flasher for the turn flasher for a test of the circuit. The flashers should be mounted side by side in the fuse panel - just exchange them and test. If so, keep the emergency flasher there and take the turn flasher in to replace. The parameters should be the same so you can just leave the E. flasher relay in place and out the turn flasher where the E. flasher was.

The emergency flasher switch is also the turn signal flasher It pops out of the dash and can be replaced easy. do chaeck the fuses before going to this much troble. check all the fuses as some work backup circuits that you wouldn;t think would be important. Before replacing the flasher switch ( you may only be able to buy it from the dealer) work the switch several times and the flashers will come on cheak to see if allthe lights work thenturn the flashers off and see ( with the key on if the turn signals now work. Now if during the test with the four way flashers you see a bulb or more out you know that the turn signals wouldn't work, but the four ways will. they work on different fuses so chak the turnsignal fuse too. after cycling the switch try the turn signals again as the switch is likly to stick and sometimes cycling it will get the turn signals working again. Fooling around with the switch you may find a position that the turn signals work. if you can't get it to stay working then you'll have to change the flasher emergency switch.

Sounds like the flasher unit to me. Normally the emergency flasher and turn signal are separate.

The directional switch is bad. The wiring has a short it seems in your case

check and replace the flasher unit if necessary, sometimes located in the fuse box area, sometimes under the dash near the steering column

Your F--150 has 2 flashers, emergency and turn signal. Both are mounted on the fuse block under the dash. The turn signal flasher is mounted on the front of the fuse panel, the emergency flasher is mounted on the rear of the fuse panel. so replace the turn signal flasher should solve the problem. Let me know how it goes.

i can tell u this the multifuncion switch is in the steering colum signals,highbeam flash to pass and wipers chuck
