There are a number of things that could be wrong here. The best way to troubleshoot electrical issues is to work your way back from the device, in this case the lights. Make sure the bulbs are good. If the signalS both stopped working, I imagine all 4 did not go bad simultaneously. The next thing are the relays. These are located under the dash. There are also some in the fuse panel. Check you owners manual for application. The most likely culprit ona 20 year old Ford is the control stick itself. The contacts get all crummy and will open circuit the signal to the relay. You can sometimes get away with cleaning them, but the best bet is to replace since you have already gone through the trouble of getting into the steering column cover. Remove the column cover (there are phillips head screws underneath) and take off the top and bottom plastic cover. You will see the box that houses the turn signal controls. Disconnect the wiring and remove/replace. As I said, you can try to clean the contacts, but I recommend replacing it. If you can find a NOS, OEM replacement or one in good, clean working order.

I assume the fuse has power if the hazards work.
The third brake light skips the turn signal switch, the regular brake light circuit goes thru the turn signal switch.
Do you have power going into the turn signal switch on the red lite green wire from the brake switch ?

1992 Ford Ranger Turn signal/Hazard light issue


Can you just check to make sure the ignition key switch is not staying over to far and not backing off when you try to start it. I had a truck that did that and it messed up my turn signals until I brought the key switch back a little after starting it. Just a simple idea. Be kind with your rating for me. Raz

1988 mustang gt no turn signals ,hazards ,wipers,parking lights all work...checked relays,fuses,fusible links and grounds.....help!


More then likely its going to be the turn signal switch itself. With everything else working, the switch fr the signals probably wore out. Keep in mind the car is 21 years old.

1988 ford mustang. Turn signals do not work


You did not say if its one turn signal or all turn signals that dont work. It could be a bulb.One bad bulb will cause the others not to work , normally one side of the car.Mostly left and right sides of the car is on a different circuits.
If it is all of them not working , it could be the switch in ur steering colum thats bad.Its the switch that the handle u move to turn the turn signals on and off.You would normallytake off the steering wheel to fix that switch.But its a bigger jpb , a pain.So make sure its not a bulb or a fuse first and make sure ur useing the right amp fuse.If its not that.Then id check the conection where the bulb screws into the socket.There can be corrosion there and that can cause a bad conection.Besides a bad bulb thats always been the number one reason my turn signals have not worked.You just have to keep eliminating the possibilities. Keep checking.

Turn Signal Flasher location in 93 Mustang GT


The flasher is a small round plastic cylinder (unless replaced with a metal one) behind the left edge of the glove box that will look similar to the one in the fuse panel. The first step is to squeeze gently both sides of the open glove box and let it swing downward. It will be snapped into a metal horizontal brace just to the left of the glovebox opening by a small tab and have two wires attached. The number more than likely will be a #552 although I have seen a factory one with a Warner #224

No turn signals


Have you tried replacing the flasher? They're typically round, and with the fuses under/in the dash. They probably cost 10-15 bucks, usually available at your local autoparts store.

your turn sig switch in the steering column is probably worn out and needs to be replaced, have a steering column specialist come out and fix or go to the dealer.
