Re: Offside repeater
Easiest way to find out which one is to take the fuse panel off and put the indicator on that is working, then follow the clicking till you find out which one it is. (mine was very top left by your right knee). if you then move the indicators to the one that isn't working and the clicking stops, switch off, take out the relay (a pull and a wiggle) and replace and try again.
If it still doesn't work then you'll need a new one (£40 from Mag) or a S/h one if you can find one. I managed to get one off ebay for a tenner.
