Loud buzzing when applying brake
I have a 2007 Fleetwood 325rkts. I have never had previous issues. Now I have purchased a 2020 GMC 2500. After connecting the camper to check lights I have a loud buzzing coming from under the cabinet...

Doug, Was able to find the box causing the buzzing. Looks like something you were refrencing. The box does split the stop and emergency lights to make the 3rd stop light work. I dont really know why it is there, I am not seeing it on new campers.It doesnt look like GM is going to be able to tell me what was done to cause this to happen with the new truck. I am either going to have to put up with it or rewire the lights on the camper.Thank you for responding. Larry
