When l push the stalk down l get no response at all no indicator light no turn signal on the left side canceling with the wheel works properly and the right turn indicator works properly as well. Whats the problem here switch itself? tried replacing the fuse but no luck.

Switch or relay is bad.

Sometimes it is the bulb.

Loose Wire
Dead bulb
If there are separate fuses for each side Fuse

You will go in circles.

check the flasher unit on that one we use to own one of those and it was bad to burn out flasher units,id also check the socket where the bulb goes in at,and the ground wire for that side,on those cars ground wires was a real problem we now own a fiat strada and its been real pain with the wiring on it,good luck.
