The front driver signal doesn't work.

This happens often on Fieros. It turns out that the clamp that holds the brake hose rusts. The rust presses against the hose, restricting it's flow. You don't notice when the brakes are worn and basically not working, but after repairs you get locked up or overheated brakes. Remove or replace clamp and or hose.

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.

check your wiring harnmess and make sure bare wire is not touch other wire this will call to flown fuse.

Then the turn-signal bulb on that side is most likely burned out and you will have to replace it.

The fast signal flashing indicates that you have a burned bulb (or one of the bulb elements is burned).
Based on your saying it's the front one on the side your flasher control is set when the signal light flash faster

By a new bulb light and replace the faulty one
hope it will help

Sounds like you need to replace the drivers brake/tail light.

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

Yes it's a bulb. Open the hood and remove the phillips screw. Then carefully wiggle the fixture out to reveal the bulb and plugs.

replace flasher......usually located in fuse block area...listen in this area....select passenger side ...then select driver side...you can hear flasher clicking...you have seperate flashers for each...FLASHERS are small cubes plugged into fuse block....probable bad driverside flasher

What may have happened is either the headlights wiring or the parking lights wiring somewhere along the wiring fused to the left turn signals wiring. Depending on if the turn signals go on when you put the parking lights on or the headlights on.

If the signals come on when you turn on the headlights than you only need to locate the light green wire that comes off the left turn signal harness.

Next follow that wire the entire way back to the firewall looking for another wire fused to that wire as you go.

If there are no signs of this you need to continue looking on the other side of the firewall all the way back to the turn signal and hazard flasher unit which is a black box that connects to a black harness located next to a grey harness behind the knee bolster.

But if the signals come on when you turn on the parking lights than you will also need to check the wiring from the rear left signal and follow that light green wire all the way back to the turn signal and hazard flasher unit.

This should fix your problem, but if not than your problem may lay within the the wiring between the turn signal/hazard switches and the turn signal and hazard flasher unit.

Also you may have a burnt circuit in the junction block. This block is where the light green from the rear left signal and front left signal meet. Don't have a description but if you cannot find it let me know and I will go out to the yard and look myself and let you know.
