Well this has just recently been mentioned when another member asked
about their indicators too.

Anyway the indicator flasher unit is situated behind the dashboard
clock/pod.  Yes the 2 pack pod as your Mini is a Clubman Estate?  But
before you go mucking around, has your Mini Clubman Estate got a hazard
warning light switch and system fitted?  It should if it's a post 1976
model?  If it has try this little trick first and switch the hazard
lights on, then with your ignition on click your direction indicator
stalk either left or right as if you were switching your indicators on
too.  Then finally with your ignition still switched on and your
direction indicator on (clicked left or right), "turn off your hazard
warning light switch".  Well sometimes this forces the indicators to
work and it's worked for me a couple of times on different Mini's

As for the flasher unit well the haynes manual recommends you pull the
fascia (clock surround pod) off to get at it, but you need to be very
careful as the pod and plastic clock/speedo mount behind is very easy
to break if forced and the fascia pod is a bugger to refit afterwards
too & the 1275GT type with the rev counter is even more difficult.  But
if it does come off with gentle pesuasion then your lucky (even though
refitting using those damned clips is a nightmare), if not don't force
it.

So I've always stuck my hand underneath the dashboard and reached up to
grasp the little silver cylinder which is the indicator flasher unit to
remove it from it's little mounting bracket.  It has 2 spade connectors
running off it and is then easy to replace.

Failing that you can peel back the dash liner from around the clock/pod
(you'll have to first undo and remove the air-vent nearest the
clock/pod) and undo the screws mounting the whole clock/pod unit and
then pull it away without disturbing the fascia or the clips.  This
again is a fiddly job but I'd just stick my hand up under the dash and
route around for the flasher unit myself.

I think someone also said that if the hazard warning light flasher
(mounted on the right hand side of the engine bay bulkhead) is
corroded, this can cause your indicators to fail too?

Good luck!

Sorry just re-read and no your 1972 model won't have the hazard warning
lights, so have you checked your fuses?  You've only got a few to check
and is everything else electrical working as it should?

I'd post details of the fuse box rating and stuff that I have, but it
won't relate to your Mini.
