My turn signals are NOT working, but emergency flashers are. Any ideas? They just went out today-- wondering if it's 1/ fuse 2/ turn signal relay or...?

have you checked the turn signal relay! It is above your left leg under the fuse access. under dash. do your emergency flashers work, because the relay is a combination relay for e-flashers and turn signals. if the flasher unit is ok, you may have a bad bulb or a short to ground.

Do the emergency flashers work? If they do the turn signal flasher relay is probably bad.There should be 2 one for turn signals and one for emergency flashers. What you can do if emergency flashers are working is turn them on and see where the clicking is coming from.The 2 flashers are usually very close to each other.

TURN SIGNAL FLASHER IS LOCATED BEHIND LEFT SIDE OF DASH, ON FUSE/RELAY BLOCK BRACKET.

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.

Do the emergency flashers work? If so the turn signal flasher relay probably went bad. If flashers are not working either may want to check fuses.

There a two modules 1 for the turn signals and 1 for the flashers. Look under your dash around the steering wheel and fuse box area for one that is in the wiring harness.

i have a similar problem but my left signal works, when i turn the right on it just does an annoying buzz sound. if you can think of any explination for such shinanogins help would be greatly appreciated

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.

Hi,

If I understand you right based on your post/description, the signal lights would still turn on even if any or both of the flasher relays are removed. Should this be the case, then the signal lights are not getting the power from the flasher relays but from the brake light circuit.

Perhaps your concern is not with any of the flasher, but simply missing or loose ground more particularly with the rear lights. Perhaps you could try determining which of the wires for the brake lights and signal lights (as they come out of the light assembly) would be ground . A test and even possibly a temporary workaround is to hard wire a second ground connection from the determined ground wire of the lights and attach it to any conveniently located bolt or screw to the body. it may be to your advantage to do this on all the rear lights assembly.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Check the flasher under the dash to the left of the steering column. It's got about 8 or 10 wires plugged into it.
