Car flooded, now audio isn't working - 2016 Mazda CX-9 Grand Touring
The car has been completely aired out, all carpets and sub-carpets removed for 3 weeks. I am not asking for flood advice (unless you can tell me how to get rid of the river smell), I just need help restoring audio.
I bought fuses off of Amazon, so idk if they're shitty quality and that's the issue, but every fuse related to audio has been replaced (2 in cabin labeled Audio and Interior) and 3 or 4 in the engine bay. Still nothing.
I took apart the doors and verified that no water actually got into the speakers or any wiring within the doors, so I'm wondering if floorboard wiring has any connection to the speakers? Everything else electrical works. I also used dialectric grease for any connections that were under water.
The audio system has been reset to factory settings. The radio and bluetooth both do not emit any sound whatsoever.
Honestly, my mind is fucking boggled. I'll take it to the audio guys soon, but as I'm unemployed, I'd like to try at home first, so any help is deeply appreciated.
