Hey guys I have an 04 I decided I wanted to switch over to led signals. I got a lm487 led flasher that fixed the hyper flash but with the front signal bulbs switched to led and the parking lamps on they won't blink. When you hit the signal lever or 4 ways the arrows on the dash light up dimly and they just stay on solid. Turn off parking lamps everything works as it should. Any ideas?

If it's not the GM LED flasher then that is more than likely where the problem is. If you switch back to the original flasher unit and every thing works like it should (other than hyper flash) then the problem is the LED flasher.
Your nearest GM dealer will have the one they usually sell with chassis trucks. About $100

No luck with stock flasher. With headlights on signals stay on solid with both arrows dimly lit on dash, headlights and parking lights off signals blink with hyper flash.
Mine did this when I pulled the bed. Turned out to be a loose connector under the bed for tail lights. Might check your connections
