Speaker Connection In and Out (Sprinter Chassis Issue?)
Hi! My 2017 Interstate 24GT has speakers that go in and out, randomly going between a weak connection, a very weak connection, and only static. All of the chassis and house speakers are equally affected. All audio connections are equally affected--radio, CD, Bluetooth, etc.
This sounds to me like an issue in the chassis--maybe a loose connection? Perhaps the radio harness in the chassis behind the entertainment/nav system?
I'd really appreciate advice from anyone who's tackled this before. I'm thinking that this could be a DIY rather than turning it over to the Mercedes dealer.
