Disco 2 Discovery 2 fog light flashing with Passenger side (LH) indicator

hi all,

my discovery2 td5 auto which is a 10p / pre face lift / 2000 year , has a problem with the rear indicator which causes both rear fogs to flash with the left hand side indicator is on but not the right the right works fine, i've pulled the fuse out for the fog lights and its obvs getting powered off the left hand side indicator circuit and i have changed the relay with the rhd side one and still the same, anyone had this issue before or can point me in the right direction.

thanks
will

I'd check all earths and all bulb holders.

The problem is most probably in the rear LH cluster's connector earth(black wire) which doesnt get to the bulbs(the middle male pin in the holder is pushed inside and not touching the female pin) so it closes to earth through the other side's fog bulb, remove the cluster's cover and push the thin metal or if that's OK the next suspect is earth header C0707, check it's connection to body and contacts in it to not be corrosion especially around pins 6-7 but that's not so common
