This Fiat Ducato had an usual indicator fault where the indicators would only flash when the ignition is switched on. The hazard lights would not funtion. When striping down the dash when come across the orignal indicator module which was the only module which controls which controls all the indicator bulbs and outputs on the vehicle.
Apon testing the switch module the inputs and outputs where all funtioning correct. It was deemed the indicator control module located in the centre console was faulty. The Fiat Ducato is a big strip down in order to go get to this module sadly.
