try under the dash above the steering colum

Did you check fuse? Reference owners guide. If you can check for voltage at fue, stick paper clip in fus slot (red, positive lead) negative lead to chasis. REPLCACE ALL LIGHT BULBS AT ONCE then have some one push brake while you hold brake bulb in your and watch to if it blows, if not turn key to on flip turn signal see what happens let me know what you see, Good luck

The dash and tail lights are on two different circuits, and the brake and turn signals are on different circuits, so at least 4 circuits total.
I would start at the headlight switch and check for power on the first two issues.

where is the location of the headlamp relay on a 2001 Buick century

Time to change the flasher unit, it's usually close to the drivers side of vehicle and behind a fuse box access panel and will have something like "12v 23/98W " on it. It's a largish cube shaped componant and may be water damaged !

This means you have a faulty relay. The relay is what causes the light to blink. They are usually a black plug that is in one of the fuse boxes, usually the one under the hood

The cause of this may be the turn signal switch, the circuits run through this switch.
