There was a recall on the 'multi function switch' on my '00.
I'm not sure about other years...
There was some defect with the switch, where the connector would
come loose and cause all kinds of problems. In mine, I lost my
main brake lights. The third brake light would still work. I
forget about the directionals, but the hazards definitely didn't
work. They would stay on solid, but nothing out back.
I found that if I pushed the red hazard button to the side,
everything worked great. I jammed something in there when I first
found out about the problem. A new switch went for something close
to $300 at the dealer. There was a TSB out at the time, and I
heard there was going to be a recall on the trucks because of the
failing the brake lights... so I waited for that to come out before
I got it fixed.
I have exactly the same problem going on on my 1999 Yukon truck for
about a week now.
The brake lights function but only when the headligths off. Other
thing is that when I brake or turn during the day, the dash and audio
unit lighting flash repeately.
At nite time, the brake lights do not function at all and the turn
signal do not flash as well. My mechanic could not figure out what
May be someone in the group experienced the problem before?
Please keep posting
I don't have any trailer and no new connection have been made to my
truck for a while. I just remember that when all this started , my
dash ligths were flashing everytime I brake or activate the turn

Yes I replace the bulbs when this problem started and no change so
far. The bulbs as source of the problem are ruled out.
Now the dash board and audio system lights flash at the same time as
the left turn signal is activated and when I brake, the dash board
and the audio system ligth up. Very weird situation
