Turn signal issues, intermittent problem has me confused. When I turn on my left on 2004 Chevrolet Silverado 1500

when I turn on my left turn signal, the emergency flashers come on. It doesn't always happen but does seem to be getting worse, any ideas? I looked for a turn signal relay and can't find it?

if its blinking fast you have a burnt out bulb
Not a bulb, The emergency flashers come on when I put the left turn signal on. Thinking a bad flasher relay, I can't locate it, or a bad turn signal switch.....
