Vehicle was not in a rain storm, only washed with care. Have had the vehicle since 2011, first time it happened the radio was shut off but full volume static and not until 2018. Radio off - blinker engaged will sound off radio, so load I think the speakers are going to blow. If key in ignition and the door opened radio blasts, if lift gate is opening or closing- radio blasts; I pulled the power plugs out of all four doors and reinstalled them. Still blasts out sound from radio. The blinker noise is only loud when the radio is blasting.
