I have an 06 Solara convertible. Recently, if I sit and idle for more than a couple minutes, the windows will randomly go down by themselves. Started with the passenger window, after rolling it back up multiple times, I hit the window lock and that stopped it. But then the drivers window did the same thing, and of course there's no lock for it. It was a rainy day, so I thought maybe something got wet that shouldn't have. That was a couple weeks ago. After a day or so, it stopped. Today it started happening again with the drivers window. The only way I managed to get it back up was to park the car for about 15 minutes, roll it up, hold the button while I was driving until I got home, then shut the car off while it was up. Any suggestions? No clue where to even start with this one. Thanks

The window controls in your door(s) got thoroughly wet, it is entirely possible that water managed to creep under the membranes that are supposed to keep it out, and all the more likely if they have developed hairline cracks over the years.
The behavior you describe has not happened to me in my Solara convertible, but the exact same thing happened in a Jaguar XJ8L I used to have, twice, and in both cases it was the result of the main window control module in the driver's door having gotten very wet and water creeping in under those membranes. And once it gets in it takes a lot longer - a lot longer - for it to ever get out again.
In my case, I pulled the door panel, removed the module, and carefully peeled off the protective membrane to allow the electronics to have several days drying on a warm, sunny windowsill. After everything was thoroughly dry, all went back to normal (both times).
It can also help to disconnect the battery and leave it disconnected for several hours as a first step, as the electronics for these cars are, essentially, a multiplexed computer network and once something "goes wonky" it can stay that way until and unless power cycled (completely power cycled - which is why you need to leave the battery disconnected for several hours to overnight). But if a damp control module is the actual root cause, you will still have to dry it out.

Thanks for the input! I tend to agree about getting wet. Problem hasn't recurred...yet. But I've also been very mindful about not sitting idling, too. I guess if it becomes a significant pain in the rear, I'll pull the door apart. Once it gets warm again. Had the top down all weekend and today it's 30 degrees again.
It's all a matter of where the water is settling in the window control ECU.
The real fix is making sure that your seals are good, particularly the wiper seal on the outside bottom of the window. If a crack develops anywhere along it, or it deforms and lifts away from the glass, you have a direct line between water and interior of door.
