Left turning signal blinks rapidly

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.

Check front signal bulbs.

sounds like one of light bulbs was malfunctioning and caused the flasher unit to blink rapidly and iy burned out. Replace front and rear turn lite bulbs and see if flasher flashes. if not check fuse and replace fuse. If fuse okay replace flasher unit. Good luck

One of the bulbs is not working. Check and fix.

you will need to inspect all of the left side blinker bulbs one of the bulbs that is supposed to blink is bad my buddy has a caviler that had the same problem one of the bulbs ended up being bad it was the rear drivers side bulb. there is also a flasher relay locater under the dash that tends to go bad just listen for the ticking and replace the flasher the flasher costs about 8 bucks at you autopart store ask for a flasher relay. i hope this helps.

REPLACE THE TURN SIGNAL BULB THAT DONT BLINK.MOST OF THE TIME IT IS THE ONE NEED REPLACING.

Sounds like a burnt out bulb, that fast blink is to tell you a bulb needs replaced.

This may have more then one bulb in the front or possibly a bad socket try wiggling the new bulb in the socket to see if it will work.Compare all turn signal lights that come on the passenger side to those drivers side.Some vehicles also incorporate sidemarker lights with the turn signals.

I just had that problem with my jeep cherokee and either your bulb has burned out or it is burning out. Time to replace it. Turn the signal light lever on the side that's flashing fast, get out of the vehicle and look at the front and back signal lights and replace the one that isn't blinking...hope this helps.

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"
