E30 Zone

my indictors have stopped working,
checked all fuses , none blown,
also the hazards arent working ( are these on different fuse)
was working fine,
ive put in a head unit as car didnt have one, but im pretty sure the indictors where working on 1st drive after i fitted stereo,

ive now checked fuses and removed head unit , and still no indictors ??

big thanks in advance chaps

While the hazard switch plug is off, try linking a few pins with short lengths of wire.
Link the blue/red (2) or blue/black (6) to the green/yellow (4) and link the red/white (3) to the green/purple (5).
This should make the indicators on one side of the car flash.
