[dirty hands]

I think some one has been there before you

give me a day

yes I do have a wiring diagramme I can scan it in as soon as I find it
the repair manual is in my many boxes of repair manuals

possibly a mixed wire behind the hazard or at the turn signal lever or relays

a short would blow the fuse - but if it has no earth - no completed circuit
are all the exterior indicator bulbs working ?
what relay works what ..... try one at a time
the turn indicator switches and the hazard switch can be faulty
