this is a common problem with all 4th gen, F-Bodies, the problem is the one of your taillight sockets has shorted out.
Normally the Black wire of the three wires which is the ground wire. Some can be fixed most can't it is inside the socket. Best bet is to find a 93-97 f-body,(camero, firebird) in a junkyard and cut the sockets out, and splice and replace one at a time til you find the bad one.
You can test for a bad one if you have an ohm meter. Inside the socket there are 3 metal strips, 2 in the bottom, 1 around the inside, check to see if the ground(black wire) is 0 ohms from more than 1 of the strips, if 2 strips show 0 ohms, that socket is toast.
Make sure when you cut the wires on the junkyard sockets you have at least 4-5 inches of wire. The more the better.
I am not sure what all of the symptoms are, but if your turn signals work at times, or flash rapidly at times, the problem may be just like the one I had with my 1999 Century. I found after gaining access to the dash thru the removable panel on the driver's side, that the flasher assembly was bouncing around inside the dash compartment. I could recreate the symptoms every time I moved the flasher assembly and attached wires. I secured the flasher to the inside of the panel using a zip-tie, and have not had a problem since. I could not believe how easy it was to fix, after spending hours checking all the bulbs and sockets and wiring.
One headlight not working
Check/change the fuse associated with the blinkers.
A bad ground wire is the most common cause of turn signals and brake lights not working. The ground wire connection might be corroded.
You might have a short. You would need to take you car in to a shop to find they short. They can be very difficult to locate.
check your bulbs
Replace the bulb.
Yes, but the buyer must be informed.
Try and replace the blinker switch. Iits a round thing under the dashboard on the fuse panel. It should be clearly marked.
your blinker will turn on but not blink if a bulb has gone bad on that side or if your relay or fuse has gone bad
If the blinker is not working on a Mazda 121, check the turn signal flasher. If the bulb needs to be replaced, remove the lens cover and insert a new bulb.
The dash indicator goes out to let you know one of the external lamps are not working
when you flip your blinker on, a relay in the circuit is activated which turns the light on and off. also, the front blinker and rear blinker usually alternate in turning off and on, so when the back is on, the front will be off, and reverse.. that's why when a bulb is out, the clicking sound in the vehicle goes faster than when both are in working order.
the light burnt out and you need a new one?
Replace the tail light bulb from inside the trunk after pulling back the carpet. This should probably fix your blinker too.
Left and right stopped working? Check the fuse and/or the flasher relay. Only the left or the right stopped working? Check the bulbs.
Your light has gone out or a bad fuse
Check the bulbs, check the fuse, check the flasher relay, in that order.
When blinker is blinking too fast it usually means one of your turn signal bulbs are burnt out. Check if bulbs are working. If not replace blown bulb.
blinker are you serious? BLINK !
Maybe your blinker realay is out.
A burnt out signal bulb, a faulty blinker relay, a faulty blinker switch, a loose connection or a broken wire are all things that can cause the turn signals not to operate properly.
There might be a break in the wiring.
How about a malfunctioning brake light switch
Check for corrosion on the connector or attached wire.
try replaceing the fuse or flasher unit.
