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?
