This could mean that one of your bulbs is blown on that side. Check and replace the blown bulb.
Check bulbs Replace flasher
It sounds like you have a turn signal bulb out probably the left rear.
It means that a bulb has burned out!
If both sides (right and left) don't blink on and off, the blinker "can" may be the culprit.
One of the bulbs is burned out. Turn on the blinker and look at the front and back turn signals to find out which one.
Is the bulb burnt out? Change the bulb and it will blink at the dash and light. If it still doesn't work, check the turn signal relay.
Bulb is blown. Replace bulb.
I am so sorry to tell you that i cant answer your question but i would if i could
First, check all of the bulbs. If one of the blinker bulbs in burnt out it will cause it not to blink on the side where the bulb is located. You have a defective Flasher Relay. Located behind left side of instrument panel.
No it means you have your left blinker on. The right bulbs have nothing to do with the left blinker. An incandescent bulb either works or it doesn't. There is no dying out.
The Blinker relay is shot, You can get a replacement one for like $3 at your local autozone.
Left blinker= [Right blinker= ]
