The Civic generation before yours did not use a relay for the
headlights, and neither did the generation after yours. I have never
seen the wiring diagram for the '90 Civic, but doubt it uses a relay for
the headlights.

When you say that the high beams work right away, are you talking about:

A). Using the "high beam flash"

B). Switching to high beams after the low beams have come on

C). Switching to high beams before turning on the lights, then turning
on the lights.

Unless you mean "C" I would say your light switch is the culprit. You
could try cleaning it with contact cleaner (and lots of it) but you
probably need a new switch.
