LIGHTS/BATTERY

1993 Buick Roadmaster

Electrical problem
1993 Buick Roadmaster V8 Two Wheel Drive Automatic 130880 miles

My twilight sentinel and daytime running lights drains my battery if I leave the switch on overnight; however, once I charge the battery the car starts and the daytime lights work, but when I press the power door locks to lock they fluctuates til I hit the keyless remote. So I have been keeping the twilight sentinel off and the battery is good the next day. What's wrong?

Have you had the body control module tested?
