Soooo.....my wife left her 2015 JKU out one night recently with the freedom tops out. And it rained that night. Alot. And as a result we now have some non-functioning equipment. First, the radio touchscreen wouldnt work, but functioned fine when using the dials. That seems to have dried out and now works normally. However, of all the steering wheel controls, only the cruise control still works. No audio controls, channel change controls, info menu and even the horn are no-go. At one point, the headlights, directionals, and wipers wouldnt work, but have returned to normal operations.

Its been over a week since it got wet and I've vacuumed the rugs every day with a Shop Vac ever since. I find it hard to believe that enough water could have gotten in to ruin whatever electronics control those functions, but I guess its possible. Is it possible that there is a fuse somewhere that may have just popped?
 
It's happened quite a few time over the years where Members have left the tops off and it has rained. Leaving the doors open and putting a fan blowing at the steering column can help to dry out the Multifunction Switch.

Quite a few functions are controlled by fuses on these Jeeps, you'll just have to check the fuses to see if there are ones for the things not working.
 
I had the same problem but only the radio screen was affected. It's a 50/50 chance that it comes back everytime I start it. It's been a few weeks now. Right now its just a neusants, but I may look for a replacement if it doesn't clear up.

I bought our JK knowing the radio was shot.

I checked the fuses...all good...

It wasn't until I found the entire contents of a 16 oz tube of clear silicone in the freedom top gaskets that I realized the radio problem was a symptom of a larger issue.

We replaced the front gasket...that slowed it down a touch. Still leaking enough I'm leaving the cheap $15 Walmart radio I installed until I can figure out the issue.

Sure would like to know what to try next. Latches seem fine...I see some billet options...but those look like bling and not a fix.

Wish there was a third latch option for the center.
