I've got exactly the same problem. Bravo 1.8 HLX, the indicators seem to please themselves when they want to work, same with the hazards. All seemed to go wrong when I plugged a bloody Xmas decoration into the cigarette lighter. The lighter/fan fuse went almost straight away, then about a week later the battery died and now the indicators are playing up. Enough to bring on the bah humbugs, never again!
Going to give the flasher relay a go tomorrow if I can find it, apparently the blue one under the steering column?
Anyone else fixed their probelm yet? - I'll post on how I get on....
Cheers
