How do I fix turn signal lights

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.

Wild guess, in the process of fixing the tail light, you disturbed the signal connections. Go back through your work carefully, see if something is loose or bad connection.

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.

I think the flasher light and the actual turn signal light are two different lights..take the flasher bulb out and put it in the place of your turn signal light and see if that works..hope that fixes your prob

first check signal lights fuses if none of signal lights work.if fuse okay,check for burn out bulbs.if all is good turn signal switch is bad or you have loose wire to signal switch if your turn signal lights work some times.

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

The turn signal switch is most likely the problem,but change the flasher for the turn signals first,some times this is all that it is.

YOU HAVE TO REPLACE THE TURN SIGNAL SWITCH.BECAUSE WHEN IT GOES OUT.SOME TIMES YOUR DIMMER SWITCH STOP WORKING.IF YOU GOING TO FIX IT YOUR SELF BESURE TO.DISARM AIR BAGS FIRST.
