First of all. This all started after i had to jump my truck a few weeks ago. My battery was completely dead bc an aftermarket light was left on. Audio static when vehicle is first started. When i start my 2014 silverado the radio comes in and out with excessive static. Same when the seat belt dings. Turn signals and brakes seem to make it clearer when they are applied. Radio eventually clears up after 10-15 min. when the truck is shut off And the radio is on before i open the door, it works without any fault
