2010 Toyota Corolla wipers, windshield & visibility problems

I was driving to work when suddenly thick smoke started appearing from the driver's side power window switch. I immediately pulled over and got out of the car. The smoke had the typical smell of burning plastic and the front passenger window slowly opened on its own. After 5 minutes, the smoke stopped and I continued to my office as it was nearby. Later in the evening, upon removing the switch, the melted plastic was clearly visible.

Tl* the contact owns a 2010 toyota corolla. The contact stated that the shield sealer that protected the front windshield and rear window were deteriorating with water bubbles and cracks. The vehicle was taken to the dealer, but was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 30,000.
