Thanks for your help, blackop555. I found the problem. Would you believe ants! Yes, tiny ants! They had gotten into the fuse/relay box and into the relays - 3 of the relays didn't work. I pulled them apart and 2 had ants squashed between the coil contacts, the other one the offending matter fell out when I opened the relay cover. There were ants all through the fuse box. As soon as I had cleaned the relay contacts, they worked again! I HAVE seen this before, in the Northern Territory of Australia. The ants seem to have a liking for small electromagnetic fields.
