Could the bulbs have blown/failed.
Dave: regarding point number 6 above, if you take a close look under the driver seat, you should see a pair of wires that run from the seat belt and disappear into the transmission tunnel. They are fairly long to allow the seat to slide back and forth and also have a flimsy plug and socket to enable disconnection if ever the seat has to be removed.
It is very likely that either the plug and socket have pulled apart, or the cable has been damaged by being caught in the seat runners.
