Rapid turn signal flashing occasionally

[tobiasg1995]

What would cause an intermittent rapid flash with my turn signal on one side? This is on my 06 gmq, standard bulbs no LEDs. I've checked the bulbs, all are good. Would a loose ground cause this or possible bad connector? Yesterday it was acting up, and this morning they were fine.

There is no off position on my genius switch.

One of the bulbs is failing at times or yes one socket is losing a ground. When it is going fast you should see a difference in one of the lights.When it is doing it put on the 4 ways and compare all the lights. The flasher goes fast when there is less current draw.Must have three bulbs ( one front and two rear) working correctly to flash normal.

Thank you for the info, I'll check into it when I get home.
