The van is due for its MOT this week and I've just been doing the pre checks. Not sure if this is a failure fault or not. When I put the hazard lights on I get an initial flash on the warning light on the dash and that's it, it does not continue to flash with the external lights which work perfectly well. I have cleaned and tried checking all of the connections at the back of the switch but they seem alright. The indicator lights work on the dash console as well If the indicators work and the hazards work on the outside does it matter about the hazard switch not flashing.
