Wipers/Headlight problems

I have a 2003 Mercury Grand Marquis. Last week the wipers would not work except on the fastest setting. The washer would not work either. Mysteriously they all now work correctly. This week for some reason the low-beam headlights are in the "on" mode during the day--even when in full sun even though I have the control set on "auto". When I turn the headlight switch from "auto" to manual there is an 80% chance the head lights will not turn off. If I am driving over bumpy terrain there is a slight "click" "click" sound and the head lights are switching off and on. At one time I even got a sense that the key ignition switch might have a role in the fiasco over the past two weeks. HELP!
