Are there any connectors between the fuse box or whatever system it uses that could be dirty? I had a similar issue on my '62 Bel Air, and the fix was to clean the connectors on the back of the fuse box. This was after I changed the headlights, dimmer switch, fixed the grounds, etc. Check all connectors first, and get friendly with the multimeter and test light.
