Left signal not working

Get the left signal to flash fast then walk around the car to see which light isn't flashing then change the bulb or socket if they all appear to be flashing (front and rear) turn on the right turn signal then look into the front and rear lens and count the number of bulbs flashing, now do the same thing on the left. Many times there's more than 1 bulb in each lamp. I hope this helps. Take care.

If the rear turn signal lights are out, and the front lights are ok but don't blink then, the bad bulbs in the rear turn signals should need to be replaced.
Or there could be a bad ground connection.
Also, there may be two relays for front and back lights.
Hope this helps.

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

The fast blinking is usually a bulb burned out. Replace the rear bulbs. If this is not the problem , it may be a ground issue, but it really does sound like a bulb issue. Also inspect the light socket while you are there. Look for any bad corrosion Good luck

Hi, I have a couple of questions.
1. were the signals working before you replaced the brake light bulbs, and did you use the recommended bulbs?
2. Do the brake lights work now?

The brakes and signals use the same filaments, so these things are tied together.

Did you check to see if the bulb is burnt out?

Replace the turn signal switch. Bad contact inside causing a crossing of the circuits. When the turn signal is applied it should open the brake light circuit allowing for just the signal to work. Doesn't sound like the switch is doing it's job.

any increase in bink speed is direcly related to a bulb being burt out.

Sounds to me like a bad ground. When the current can't complete through a ground circit it feeds back through the elements ancd can cause all sorts of wierd syptoms.

The fast blink itself can be casued by a burnt out bulb I would check that first.

Then I would check the trailter harness if there is one and unpluch any harness that may be plugged into it. also check each bulb to see if it is seated well. you may be able to see if there is corrorsionaround the bulb terminals at this time is so yo may need to replace the light assembly. Also you could look for any spot where maybe someone in the past tried to tie into the harness to hook up additional lights etc. this may allo moisture in and corroded to the point the wire is "open"

clean the sockets and put in a new bulb the blinker and stop bulb have 2 different functions one may work while the other dosent
