Wiring problem left blinker does not work properly

Your bulb might be burnt since most bulbs that are use for brake light and blinker are also used for lighting the same rear position light. But have you checked the front blinker when this happens? Some cars will act this way when a bulb is burnt. Good luck

If bulb is OK;

1. Bulb has a lower wattage than the original. This decreases the load on the blinker module and makes it blink faster.
2. Blinker circuit is burned out or the connection is dirty; look in the fittings for corrosion.
3. Bad earthing can cause this problem.

Good luck!

Check for power at the socket. If there is no power I would suspect the flasher relay wich supplies power to each bulb individually after it gets the right or left signal from the switch.

IF LEFT FRONT BLINKER NOT WORKING FRONT TURN SIGNAL BULB BURNED OUT.

Hello Durant.
Your rear signal lamps are turned on by the body control module (BCM).
You could have some broken wires from the BCM to the rear signals or the BCM isn't providing power to them. The BCM must be getting a signal input because the front ones are functional.
If you want to trace the wires here are the colors you are looking for.
Left rear wire is white/dark green.
Right rear wire is white/brown.
You may need to have your BCM scanned to verify.
If you would like more information to solve this yourself ask me.

If the left turn is flashing fast then this is a sign that either the front or rear indicator bulb has blown and will need replacing once you have done this then you should find it will work properly if not post me a message back then i can assist you further ok

HI:
When your blinker blinks really fast, it is usually because one of your bulbs is burnt out. To check this, either have someone watch them, or turn on your 4 way hazard flasher and walk around the car.

it sounds like you have a bad fuse or your lights are burnt out

NO PROBLEM TURN ON THE RIGHT BLINKER THEN WALK AROUND THE CAR MAKE SURE FRONT AND REAR BULBS ARE FLASHING... IF YOU HAVE A BULB OUT YOU WILL NOT OFFER ENOUGH OF A LOAD TO THE FLASHER... WILL CAUSE IT TO FLASH FAST... IF OK THEN MAKE SURE THE PROPER BULB NUMBER ON BULBS AND MAKE SURE CORRECT BULBS USED IN VEHICLE.... IF OK CHANGE FLASHER
