Weird hi/lo beam behaviour does suggest the beam switching relay and/or maybe its connections, but this is a good time to check your headlight switch and connector. Overheating of the connector and partial melting of its plastic body are quite common in these pre-86 cars. This happened on my 83 and resulted in occasional intermittent headlights, especially on high beam.

After (for? during?) the 85 model year, Volvo incorporated a relay to take the heavy electrical load off the headlight switch and several of those cars' owners report that the overheating has now moved to the relay and its connector.
