Twin30

I download one and couldn't find anything to do with the indicators

An indicator wiring diagram would be helpful but can't find one anywhere

I have a 1991 r32 coupe I just brought but can't figure what's wrong with my left front indicator not working. I have tested with multimeter at the plug and nothing checked fuses and relay and still nothing, also my left hand signal light doesn't work on my dash, switched bulbs and nothing. Yet my left hand rear indicator works...
