If neither high nor low beams are working, you could have a bad ground
connection.

Locate the large ground connectors under the left side of the dashboard.
You will need to drop down the fuse panel to see them. The brown wires
connected to the round connectors that are attached to the body have
slip-on spade connectors. Corroded connectors here is a common reason for
electrical malfunctions, particularly concerning lighting.

The connectors are not easy to work on, due to their location. A little
emery cloth and/or a file will usually clean these connectors
satisfactorily, but if they are corroded badly you may consider replacing
them.
