Turn signals were working...but blinking fast. now they don't work at all...replaced fuse in side panel near door and still nothing. Everything else works..headlights, wipers, hazards..what gives?

Check one of your signal bulb is out check all 4 of them

Generally speaking, symptoms of a bad or failing turn signal bulb are usually the culprit...in your case, either it's the front left or rear bulb. Varies for different vehicle makes...common signs include:

1. turn signal light staying on solid
2. or blinking very fast
3. or either sides of the bulbs stop blinking altogether.

To test this, make sure you reconnect everything you disconnected.
Turn the left signal light on; go to the front of the vehicle, is the turn signal bulb illuminated? If it lights up, even though it is not blinking obviously the bulb is okay. If it doesn't, replace it- problem solved. You'll do the same procedure for the rear turn signal Is that lit up? If not replace the bulb and the problem is solved.
Another common failure is when the turn signal blinks really fast, same procedure as mentioned above.
If both bulbs for the left side and right side illuminate but don't blink, the problem is in the steering column turn signal switch.
If the left or right side blinkers don't work properly at all...then check the integrated hazard warning/turn signal flasher relay- that may be defective; again, that's usually the case if both sides of the signal light don't work.
If you are blowing any fuses related to the flasher system, you have an electrical overload in the turn signal circuitry.

check the main earth wire near the battery. and one near the rear of the lights. unbolt them and clean the connectors up put some grease on them after. then check again. remember that when the earth wires come off the radio code will be needed to reset the the radio. be safe and take the battery off.

sounds like the signal switch relay fuse. turn your signal on and check your fuse boxes... inside the car and under the hood. it will look like a little square box inside your fuse box next to your other fuses. with your signal on, you should be able to locate the relay because it will be making a clicking noise. pull it straight out and go get another one. hope this helps.

The fuse for the turn signals is located in the interior fuse panel, usually located under the dash on the drivers side although it may be behind a panel on the side of the dash on the drivers side that you can access when the door is open. The flasher relay is located on or near that fuse panel as well. There is only 1 fuse for the turn signals so if you have some of them but not all of them it's not the fuse. It may still be the relay but I doubt it. That bulb may not look burned but it most likely is. that fast blinking on the right rear is an indicator that the front bulb is burned or not functioning. It is an indicator dodge built into there lighting systems. Replace the bulb, if that doesn't resolve the problem start check the wiring and look for a grounded wire.

The circuit board needs to be replaced. Which is the board that the bulbs sit in. If you remove the turn signal bulb. You will notice the bulb socket will be slightly burnt inside. I had the same problem with my 99 Denali and replaced the circuit board for $35.00. Now everything is fine.

Need to replace the bulb. There are 2 filaments in the bulb. 1 works parking light the other is turn signal. It flashes fast to alert you that it has a blown out bulb.

This simply means that the front driver side turn signal bulb has failed. Replace it.

if i remember right the flasher is located on the back side of the fuse panel

Turn signals have a relay (its a small switch that charges and discharges current) which controls your turn signals blinking speed and interval. This is most likely your problem. You should be able to get a new one at your local parts store. Follow these instructions, in this order, and let me know how it works.

Step 1:Turn on the hazard lights and walk around the Taurus checking that all four turn signal lights are working. If any of them are not working, replace the bulbs. A non-working bulb in any of the turn signals will often make the turn signals appear that a flasher is going bad.

Step 2:
Locate the fuse box and check the fuses for the turn signals. There may be more than one. Replace any fuses that are blown and then recheck the turn signals again. If they still aren't working properly, then move on to replace the flasher. Step 3: Look for a round, silver-colored object near the fuse box. Put your finger on the object and turn on the turn signal. You should be able to feel a mechanical clicking as the turn signal blinks. This is the flasher. Step 4: Pull the silver flasher out of the socket and replace it with the new one. Each of the flashers should have two pins sticking out of the bottom side. Start the Taurus and recheck the turn signals to ensure that they work. Joel
