Firsly, climb down off the ledge. There’s a good fellow.
Secondly, welcome to “It’s a Jeep thing.” If you’re at all using your Wrangler properly (i.e., removing the top, doors, winders, and such and such), it’s gonna get rained in, and you’re gonna get rained on, if you’re atop it when it happens. No big deal.
You have a 2014, so it’s a JK. The main vulnerability to rain is the clockspring - the seam between the dashboardy extension of the steering wheel and the rotatey part of the steering wheel itself. If it gets significantly wet, the steering wheel controls may go wonky, which can affect headlights, wipers, turn signals, radio control, etc etc. If this has happened, it usually fixes itself after a day or two of drying out. If it doesn’t, or if you want to jumpstart the healing, you can disassemble the steering wheel (literally a five-minute job) and dry the contacts out manually. If the spring itself is deeply compromised in the rotatey metal part, you may need a new clockspring, which is about $150ish.
I’m usually topless, have been rained on dozens of times, have had the clockspring go mental four or five times, and in all but one case it’s fixed itself within a day or two. In the last case, it was still wonky by day three, so I took the steering wheel apart and hand-dried the contacts to fix it. And it was then, my friends, when I sat with my Jeep’s airbag in my hand after twenty seconds of work, that I found the solution to all of my financial problems! Those things are worth hundreds on the black market, aren’t they?
Thirdly, yeah, you should have plenty of drain plugs. Four or so on the bottom of the footwell, and a few more on the bed. They’re beneath the carpet, but if you bought your Jeep used, someone may have removed the carpet and coated the floorboards (sounds like it maybe?) with something else. After the second or third time you get raint upon, the smell of the carpet will compel you to take action. (I removed mine and replaced it with artificial grass.)
And fourthly, nice (former) Jeep, Johnny L.A.!
