Hi I had a driver rear indicator fault and found that part of the bulb holder had broken off. I ordered a replacement unit but in the meantime the passenger side front indicators have also stopped working. Replaced the rear light assembly but still no driver rear indicator or passenger front indicators are working. I have checked some of the fuses off watching YouTube videos all seem ok. Now I’m at a loss any help would be appreciated thanks.

I wonder if there was a short-circuit when the holder broke?
In which case fuses would be my first port of call

However, worth checking the obvious such as blown bulb and also any earth points that may be corroded or loose
