Thanks whittinghame. Checked it and all three seem to work. It randomly happens when in motion and I can only see the mirror one flashing fast, can't see the other two.

Thanks again :-)

It's USUALLY caused by a bulb not operating as it should for whatever reason . If easily accessed you could remove indicator bulbs one by one and check for corrosion , bad contacts , squirting with WD 40 if needed to clean out . Also check bulb contacts or replace bulb if one available . Annoying . hard to find when intermittent and you cant replicate the fault . I would start at front indicator as they often tend to get more rain / water spray from other vehicles when driving , Or it's possible it may be a faulty flasher unit .

Thank you again whittingehame. Would by any chance where the relay is? Just checked them contacts, cleaned them, went for a drive and it happened again.

Not sure , but on that year it may be part of the BCM ( body control module )

May be a faulty bulb holder or earthing fault . This is the type of job I passed on to my auto electrician to resolve lol .If you can get it to do it when parked , check all bulbs flashing .

Thank you very much whittinghame. I think I will have someone follow me and see the rear bulb when it acts up again. Do it again with me following the someone to check the front. Old car and trying to sort it on the cheap :-). Thanks again!
