This has happened to me only twice, but both occurrences were under very similar conditions (eerily similar, actually).

So the first time it happened was about 11 months ago. I was driving back to Daytona from St. Petersburg, which is about a 2.5 hour drive under normal conditions. Traffic was awful that day and the whole drive actually ended up taking close to 6 hours. Never doing that again...

Anyway, I was passing through Orlando around 10 pm. I was getting sleepy and the AC was drying out my eyes, so I decided to turn it off and roll down the windows. It was real humid that night, but I'd take swamp ass over dry eyes any day. Also I-4 also isn't the best place to have a nap.

I was listening to Drukqs (one of my favorite albums from Aphex Twin) with the volume cranked up to 32 to stay awake. When I rolled down the windows, the combination of a cold dry car interior and the warm humid Florida air caused a considerable amount of condensation to form on nearly every surface. Thankfully my windshield was spared from this spontaneous wet surprise, so I didn't think much of it. I turned down the volume down to inaudible levels to give my ears a break for a while. When I eventually turned it back up some time later, I noticed that there was no sound. Thinking that my phone was perhaps trying to connect to some nearby wifi signal, I turned wifi off and restarted my music app (thanks apple for programming my phone to stop streaming from cellular when attempting to connect to a weak wifi signal).
No Dice.

Tried turning the radio off and back on.
Nothing.

Perhaps the USB connection was screwy. Aux should fix that!
Aw, that's right. I bought an iPhone 7. Thanks again, Apple.

FM radio, AM, both silent. Nothing could get the sound to come back. It wasn't until I returned home and restarted the power system by taking the keys out and reinserting them that the audio finally started working again.


Thankfully, I went over 9 months without any problems like this happening again. Which brings me to mid August. I was driving up to Maryland to visit my parents. I was on the 495 beltway around DC and had been driving with the AC on. I wanted some fresh air so I opened the windows again. Once again, I was hit with condensation. Once again, the audio stopped coming through. I nearly sh*t myself when I realized that I was also listening to the exact same album that I was the last time this had happened.

COINCIDENCE?!......

...Yeah, most likely. But all the other conditions gave me a clue as to what may have caused this problem. The fact that the interior was coated with condensation both times leads me to believe that water had formed on one of the circuit boards in the audio system, maybe causing some pins on a microprocessor to short out and crash the firmware, only fixable by resetting all the chips with a power cycle.

So have any of you folks had this happen? If so, what were the conditions in your car like in the moments leading up to the problem?
And were you listening to Druqks?
