slowfkncar Posted December 13, 2019 Report Share Posted December 13, 2019 Fusions & escorts have noisy systems, some people have had luck by having the dealer flash an updated/fixed firmware in the audio control module, this usually takes care of the high pitched white noise & audible clicking with the lock/unlock switch. If they end up charging you, id say screw it and swap the unit, it will sound a whole lot better anyway. Link to comment Share on other sites More sharing options...
