Ford Fiesta Mk7 hazard warning lights not working

[TimeforTea]

Hi, just wanted some advice from the great and the good on this forum, as per the title really:- Ford Fiesta Mk7 hazard warning lights not working.
Indicators all work, bulbs all fine, when i unlock car all indicator lights come on briefly (this is normal i think), however when pressing hazard switch in car no hazard lights work. Is it really just the switch or is it more complex.
Thanks for any help
