I have started having a problem with the lights in this 1993 Grand Am
SE Quad4. When I try to switch on the lights, they don't switch on. The
parking lights come on, and the high beams work if you pull back the
stalk (flash-to-pass) but the main lights don't come on at all.

The problem started with the lights randomly going out at night. Then
they went out predictably if I switched to high beam (the CLICK after
you pull the flash to pass). They would come back if you clicked it
again, to go to low beam.

Now, I only have flash to pass. The low beams don't come on, neither do
the high beams. I wanted to check the fuse, but I couldn't locate the
one for the lights (they have such weird acronyms).

Could anyone help me out? Its a real hazard to drive without lights.
