The indicator on SWMBO's i20 has started playing-up. Indicating right is OK but the flasher sometimes ticks at double speed when indicating left
- it's been intermittent for a week or so (never when I'm around) but now seems to have gone hard. I'd expected to walk around the car and smugly point-out a dead bulb, but none of the bulbs are working. I'll check the wiring, earths and bulbs tomorrow but without a wiring diagram what else can I check?
