The problem was that the solder connections inside the relay assembly had cracked - presumably due to vibration. The fix was simple - just reflow the solder using a soldering iron and some flux (electrical flux _not_ the plumbing stuff!!!). It's probably cheaper to buy a soldering iron if you don't already have one than to get a new relay! The relay is rectangular and looks like two square relays stuck together. The cover simply clips on you may need a small flat screwdriver to prise it off, but I didn't. Once you've opened it up you will see a PCB assembly with some components and two open frame relays mounted on it. Look at the solder traces, the cracks should be visible to the naked eye where the spade type terminals are soldered to the PCB. BTW, the indicator / hazard light flasher relay can suffer the same problem. Hope this helps. AndyH '94 9000 CDE
