Headlights problem #1

2000 Mercury grand Marquis - headlights and taillights go on and off throughout the night while the vehicle is parked and the engine is off.

Turn Signal problem #2

Cruise control works when it wants to. . . . Some days it will work, other days it won't. . . Also had problem with signal light blinking faster at times than at others. . . Had that particular problem fixed by changing the "light module" for $500. . . Now its the cruise control. . . One more problem and I'm selling the car. . . .
