When you press the A button, the wipers will wipe once no matter what. If it keeps wiping after that when there is no rain then there is a sensor problem.
For the headlights, how bright is it and how long is it in the sunlight before it turns off? Or does it never turn off in the sun? Make sure the switch is on A. And make sure you're not confusing DRLs with headlights. If you have DRLs turned on, they will be on whenever the main headlights are off.
