The Electronic Throttle Control light came on-no windshield wipers, no radio,ect

What is your question?

While driving in a downpour the windshield wipers stopped working, as did the radio, windows and speedometer. First just the throttle control light was on then the tire pressure light came on then all the lights came on. I parked it overnight, started the next morning and all that came on with the engine light and tire pressure light. It also said Check Tire Pressure System. Do you know what is going on?
