Indicator faults?

Hi all, went out in my 2004 Discovery 2 last night and noticed none of my indicators were working? The green arrow on the dashboard flashes once but no more but nothing happens with the indicator lights it’s the same for the hazards. Checked all fuses and there all fine anyone else experienced this or no a common problem and a fix for this?!

Hi. Can be a IDM(interior fusebox) or BCU fault, not easy to troubleshoot, you have to remove the fusebox and open it to check if there's no visible corrosion in it or a dry joint cos water ingress is common there eventually replace the fusebox with same age one cos it's plug and play and if the fault persists unfortunately you'll have to do the same with the BCU but this one needs complex programming with dedicated tester
