I started my car yesterday and something was louder than usual. I didn't pay attention and proceeded to my destination. Then I realized that the blinker/signal is not working. Power window is not working. However, the car drove fine and AC was working. I then noticed that the doors are unlocked. I pressed the door lock and suddenly the blinker, power windows are working again. The loud noise is also gone (I still don't know what that was). Has anyone encountered this problem before?
