Do you know what a DVOM - digital volt ohmmeter is ? How to use wiring diagrams to test electrical circuits with DVOM? Do you know how the turn signals work ? What controls them ? More then likely it's a problem with turn/hazard flasher module.
Turn Signal/Hazard Lamps
The IGN E 10 A fuse in the underhood fuse block supplies battery positive voltage to the turn signal switch assembly. Ground for the hazard switch is from G302. The FLASHER 15 A fuse in the underhood fuse block supplies battery positive voltage to the turn/hazard flasher module. When the turn signal switch is placed in either the left or right position, a voltage signal is completed from the turn signal switch to the turn/hazard flasher module. When the hazard flasher switch is activated, a ground signal is completed from the hazard switch to the turn/hazard flasher module. The turn/hazard flasher module then sends an on-off voltage signal to the appropriate turn signal lamps, or to all turn signal lamps for hazard operation through these fuses:
Turn signals and hazard lights are 2 totally different switches. You basically verified that the flasher unit works, but the turn signal switch is broken.
I think the flasher light and the actual turn signal light are two different lights..take the flasher bulb out and put it in the place of your turn signal light and see if that works..hope that fixes your prob
Lots of Fords were built with turn signal flashers and on different years and models they put them in differsbt plaCES. The most modern ones with the hazard flasher switch in the middle of the dash the flasher is in the hazard switch. You have to replace the switch to replace the flasher. I've found that punching the hazard switch on and off with the car running and the trun signal on that some of them start working asgain. Parts stores have some of them others have to be bought atr the dealer. If the car as preety new I've got most of them to work some just by turning them on and off many times.
you don`t say but do the lights work either on the front/back on both sides.if not then it may be a fuse that needs replacing or need a bulb replacement.if the lights work but don`t flash then it sounds like a signal flasher problem.the flasher is located in the fuse panel under the dash on the drivers side.if the hazard flashers work then turn them on to find the hazard flasher by the fuse panel then you will know what the signal flasher looks like and change the signal flasher.make sure you change the one for the signals and not the hazard one.if the hazards work then i would say the signal switch is good as the hazards work through the same switch.
Yes your right the emergency flasher switch is the flasher and located in the middle of the dash and it has a triangle on it with a point up and a ! in the middle. It's dark red in color and when depressed lights up red and flashes ( if it's working like it's supposed to ) If the fuse for hazard is blown the flasker won't work on turn singal either. The fuse for the hazard is hot all the time and the turn fuse is only on with the key. You might find that when you find the button and push i thaqt the turn signals work normally and after you find why the flashers doesn't work on hazard then the hazards will work too.
with the hazard switch poped out of the dash ( it just pries out) it'll have lot's of wires one will be hot all the time and another will become hot when you turn the key on. the other wires go to the turn signal switch. If you find that the switch works fine and it still does flash on turn but it does flash on hazard with it on as a hazard go around and look at all of the lights. They have to work on both the frontand the back and the indicators in the cluster ( speedometer head ) If they all work and are bright ( not dim light the running light) The hazard switch is bad as it's the flasher is made into it.
The hazard lights has it's own flasher, change the flasher for the turn signals and see if that works. To find out which flasher it is, put on the hazard lights, and put your finger on the flashers, which ever one you don't feel clicking is the turn signal one.
the hazard switch above the radio is your problem. if you put on your signals and they don't flash turn hazards on then off and they will flash. (changing this *** will fix your problem
