Why does my left turn signal blink fast?


Asked by Sep 04, 2016 at 10:17 PM about the 1999 Dodge Ram 1500 2 Dr Laramie SLT Extended Cab SB

Question type: Maintenance & Repair

My left turn signal blinks fast while I use it. I have replaced all of the lights so that is not the issue. Also when I turn my headlights on my left blinker light on the dash comes on and stays on. It is a manual switch for headlight. I am still able to use the left blinker, but it remains fast. When I turn the hazards on the left blinkers work at correct speed. Please help.

change FLASHER...check/clean bulb sockets/grounds...not hard and inexpensive.


What do you mean by change flasher? I will check all the sockets.

Did this fix your problem, I have the exact same symptoms. And when everything is off, and I am out of the truck, the left from marker/turn signal stays on.


It's a bad ground to a bulb socket. With no ground, power backfeeds through the bulb from parking lamp power.
