Check the stalk. I had a 94 Achieva (Same Car),When you turn the stalk to
headlights a spring loaded clip makes contact,mine got stuck so no
headlights.
 With contact cleaner I got another year out of it.
I replaced it with a new one ($109)and guess what it was bad right out of
the box.
 You can check the switch by disconnecting the connector to the lightswitch
and jump the power to the headlight pin.the lights should come on.
***before I did anything I disabled the SIR system!!!
You will need a manual, I believe its the brown wire, I am not sure.
