Turn signal issue

My right and left turn signals flash real fast like on a car that has a bulb out.
Expect there are no bulbs out.
Any idea what problem is?

My turn signals won’t flash when i have my lights on. They turn on but don’t flash. When my headlights are off, they work fine. But first thing to do is clean the bulb contacts.I HAVEN’T BOTHERED TRACKING DN THE FLASHER RELAY UNIT YET. My Gem runs great w long range…i can manually flash my turn signals the few times a mo. I drive at night
