In my 2006 LS Cobalt the left blinker suddenly got a mind of its own. Driving today the front left blinker started blinking real fast. I looked in the rear of the car in front and seen no flash so assumed bulb. Later in the trip home it started to work, then a few turns later it didn't. Once home I checked and both filaments were intact and it blinked ok. The passenger side has no issue. I checked all others and all lamps seem fine, turned on hazards and all ok. I am puzzled and am wondering if something could be going on in the switch or should I just replace the bulbs regardless.
