Report "My 1999 Renault Laguna mk1 1.6 petrol rear left indicator does not work. The bulb is fine, the circuit board is fine all tested. But, when I turn left, indicators flash fast? Can't be relay coz the hazard indicator switch works all indicators work normally EXCEPT the rear offside indicator don't work. Bulb tested works fine? Whether it's a wiring loom problem or what I do not know? Worked fine before, now it don't!! It a big concern coz it won't pass MOT can you help please? Thanks"
