My girlfriend's indicator on her Fiesta Mk3 Si has recently fudged up. When trying to indicate left the relay clicks rapidly but no bulbs light up. All bulbs work, the relay works and the hazards work as they should.

Is this a wiring issue? It's also done it a couple of times when indicating right, but very rarely so I hope that side isn't on it's way out as well!

Any solutions are much appreciated.

Cheers.
