UK Car Repair: Renault Master indicator problem, renault master, hazard switch

Question
My Renault Master 2002 van has a problem with the indicators, they don't work at all, neither does the hazards. Can you tell me a probable fault and where the flasher unit is located. Thanks

Answer
It may not be a Flasher unit problem.  The hazard lights are fed directly from the battery at all times, the feed them goes to the indicator switch via some type of relay. Have you tried putting the indicator switch on with the ignition, and slowly operating the hazard switch to see if anything works.  Very often the problem is the feed, to or from, the hazard switch.
