CHEVROLET TURN SIGNAL BLINK FAST

My Blinker Lights Are Flashing Rapidly Front And Back. I Looked At Fuse Panel For Possible Flasher Relay And Only Looks To Be One Relay...

Rear Turning Signal Blinks Fast Inside And On Mirror I’ve Changed The Bulb, But Still Does Not Work.

Randomly My Right Rear Turn Indicator Will Say It Failed And Will Blink Fast And If I Deactivate My Blinker And Activate It Again Right Away...
