for some reason, everytime i wash my car, my brake and my battery lights always seem to stay on after a carwash. but later it dissapears out of nowhere. i check if its my brakes, and its not. i also check if its charging the alternator and it is. does anyone know wat might the problem be? and how can i fix it?

well the brake system is designed to see a fault or a shor in your case. you obviously have some leaky seals around your tails.. the alternator on the other hand, that could be a couple of things. but since you mentioned it was after washing the car, then my guess is water is getting somewhere that isn't properly sealed anymore,
