Indicators not working on dash

[f30jomi]

hi all, my e39t is having a weird issue where the high beams, indicators and hazards are all working externally, but not showing on the dash cluster.

i’ve done a dash cluster test and all seems to be working fine, was wondering if anyone else has had this issue before. been told to look into the hazard switch, and also maybe even the lcm as apparently a blocked sunroof drain may cause it to flood the lcm and cause corrosion and damage?

any help greatly appreciated!
