If you have the fusebox under the dash with 20 fuses, the indicators & headlamp flash is a 15Amp fuse in position 10. This is on the end of a row, so depending on which way round the fusebox is fitted, it will either be nearest the driver or furthest away (left hand drive car). Check your headlamp flasher and if it doesn't work, you may be on the right track.
Under the bonnet, the small fusebox has a 20A dash module fuse in position 3 of 9 (or 6 of 9 if you count from the other end).
But beware that fuseboxes will vary.
Pull a fuse out and it looks like a metal U with a moulded coloured plastic fitting. The U should be continuous. If there's a visible break in the U, the fuse is blown.
