Left blinker switch failure?

Turn the 4 way switch on and off several times. Sometimes the connection that goes from turn signals and emergency
lights get dirty.

Looks like the switch is bad,they are plastic and after time the brass contacts "sink" into the plastic. Have to pull the wheel and the lock plate but only about an hour job.

The bulbs all have to be good for the flasher to work. The flasher is under the dash, driver side. When you turn on a blinker, do you hear it clicking under the dash. If the turn light is on , on the dash , but not flashing, then a bulb is probably bad on that side. Leave the blinker on and walk around the vehicle to check the lights. Flip the blinker to the other side and walk around the vehicle again checking lights. If all the lights are lit, but not blinking, then the flasher is most likely bad.

because of no light flasher on left side the front one will go faster .maybe the left rear light is burn. and brake lights are control by the brake switch on brake pedal hardware, might be unadjust

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.

That's normally a good sign.

I'd just check them out, switch on the 4 way flasher/emergency lights and walk round the car. If they're flashing on all 4 quarters. Its OK.

The do not run off the same fuse but they do run off the same blinker. Try turning on the key, click the left/right (check both) turn signal and then operate the 4 ways on and off at the same time. Work the 4 way switch back and forth 10 to 25 times and see if you get any short winks or blinks from the system.
Turn signals are usually on their own fuse in the glove box and hazard are on with the brake fuse. If this does not work, I would look at the blinker. It is possibly bad. Check each pin of the blinker and see if there is power there when you turn on the 4 ways or turn signals. Replace Blinker. Make calls to parts stores and dealer for location of this blinker.

You most likely need a new blinker switch - the emergency flasher is also most likely bad - there is one flasher for turn signals - and one for the emergency lights --
Replacing a blinker switch is best left to the pros --
also - Take down the Vin # and call the local dealer - - ask about recalls and Service bulletins.

you need to replace the blinker lever switch the whole unit take it to a dealership if you can't replace it yourself and be prepared they cost an arm and a leg but if you can fix ityourself check out a local junk yard for amatching car to see how it comes apart b4 you tear into yours.. but also could be the flasher located deep under the driver's side
