Fast blinking left rear turn signal. Changed bulb, socket looks good
Still blinks fast. All another lights and blinkers work fine. When the hazards are on left blinker blinks at normal speed but not when i use the blinker switch to make a left turn. What next? Could it possibly be a bad turn Signal flasher? Thanks for the help.

Yes. This car has a flasher module, and not the old school flasher. The flasher module runs the turn signals as well as the hazards. In my experience, when they go bad, they go bad one function at a time. You can get them on Amazon for a decent price. That's where I get most of my parts.

It is located on the drivers side of the car, below the dash. See the attached image.

Hope this information helps. Please come back to 2CarPros anytime and send your friends too!
