I have the same symptom on a '96. There is either a headlight switch problem or a wiring problem at the fusebox. Check for melted plastic at the fusebox or heavily oxidized or burnt wires/connections. I did temporarily resolve my problem once by de-oxidizing the wires for the headlight circuit. I think quite a few of the Metro's circuits use wires of insufficient gauge and connections for the loads involved.

The bad news is that rebuilding the harness is quite a pain, but it has solved some people's problems. The headlight switch is not cheap. I do not know if it can be rebuilt.

In my case, on a very rare occasion the problem will resolve itself for a few moments. I've learned to live with using my headlights in the middle position.

There are a few posts on this and 'headlights' related issues, if you search.
