If is usually mounted near the fuse box on a bracket. I can see the one
on my wife's 95 Integra by just looking up into dashboard. Ours in
mounted along the outside wall - not the fire wall. Suspect yours is
mounted similarly.

If you are familiar with soldering electronic components, I'd take the
relay out and reflow the connections to see if that fixes it.

Here is a picture of the relay mounted in a car:
