Turn signal problem on GMC - can’t find any info

Dear Scotty,

I have a 2017 GMC Sierra 1500 work truck with 33,000 miles.  It has a turn signal problem in the mornings where it blinks fast and indicates a right front bulb problem and indeed the right front bulb does not flash.   

in the afternoons on the way home from work the blinker works normally!   It has done this for days.

I can’t find anything when I open the hood.  I also can’t find good videos or info on line.   

Is my truck telling me to stay home in the mornings?

How do I get to the connector and socket to check them out?

Replace the turn signal flasher.
