Replacing signal turn

There are a few possible reasons why your turn signal light is not working while your brake and tail lights are functioning properly:

1. Blown fuse: The turn signal lights are connected to a different fuse than the brake and tail lights. The fuse for the turn signals may have blown and needs to be replaced.
2. Turn signal switch: The turn signal switch, located on the steering column, could be malfunctioning and needs to be replaced.
3. Wiring issue: A wiring issue, such as a broken wire or loose connection, could be preventing power from reaching the turn signal lights.
4. Flasher relay: The flasher relay is responsible for controlling the turn signal lights. A faulty flasher relay could be preventing the turn signals from working.
5. Signal/light module: Some cars have a signal/light module that controls the turn signals, this could be faulty and need to be replaced.

Check fuse.

You say you replaced turn signal switch, Have you changed the relays for this? Also check chevy recalls as they have had several concerning electrical problems with these cars. The harness can also get corroded as well as the bulb sockets.

my oldsmobile 1995 cutlass supreme has the same problem, so I replaced turn signal switch.

OK try this turn the signal light on one side or the other then push brake pedal if brake lights come on replace the turn signal switch

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

replace the turn signal switch it self, mine did the same thing with the left turn signal, put in fuse and it will continue to flash... went to junk yard pulled one out of a 97 avenger just like mine, swapped them out and now it works fine. looked to be like some corrosion... to repace: 3 screws under columb, 2 screws on side of signal switch (black plastic side). unplug and replace

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
