check the flasher relay. It could making the noise, because it is arcing to the case

Not very common for the flasher to go out on our platform. I'd look at that, it's located right behind the plastic kick plate where your knees would be on left side, several screws to take down. When the plastic is down, the flasher is on the left hand side, big thing, like 3" long, and 1-2" wide. Novita makes the replacement flashers for GM, good thing is, they are LED compatible! LM486 is the part #. Good luck.
