Hi! Newbie here.
I have a issue with my Suzuki super carry van (Bedford rascal shape)
The left indicator has stopped working? The right works fine. And the hazards work. And all of the bulbs light up when hazards are pressed. There is no clicking noise when indicator is switched to the left? Could this be a flasher unit or faulty stalk? Help!!!

If none of the left bulbs are working it's probably an issue with the combination switch (indicator stalk), or the wiring to the relay.
