Headlights dont work - Please help an old woman out

[barry_mann]

A lady at work had asked me if i would look at her car. She said when she went to leave from work yesterday her headlights would not come on but her flash to pass, blinkers, taillights etc worked. So i went to her house while on my lunch break. The first thing i was going to check were her relays but i could not find them. So i went to check her switch. There was two relays right underneath the switch. So i roughed the switch up a bit and checked it, no worky. I then decided to unplug the grey relay and check it. I had power going to it then pulled the knob on the switch and they worked. I put it back together but am unsure of the problem so i have a few questions.

Where is the headlight relays located?

What relays are located underneath the switch ( 2 of them black and grey )?

Which does it sound to you, relay or switch?

thanks for any help, this is on a 1998 buick century.

Buick is great with headlights, do the high beams work? Or just the flash to pass?
