Turn light left gives me turn on both lights

[martin1234]

Hi

I have a CHEVROLET Silverado 1500, 2004, 5.3 V8 4WD Pick-up, and have a problem i need som help with. The problem is when turning left. I put the blinker handel down to blink and the it starts blinking on both sides. when blinking to right it is no problem, it is working correct. This is also a problem witch is coming and going. When having the car in the garage and blinking back and forth, it comes somtimes, but then after some blinking it goes away and works for some time.

 

i tried to open up, taking out the 4WD selector and the light dimmer to see if i could find a relay, but could not find it, and also how to take apart the stairs, but could not find any screews (to look for the turn switches)

 

Does anybody have some tips how to fix this?

Much aprisiated

Weak ground connection on left turn circuit. Maybe by the rear bumper? I'd check the rusty areas first.
