2012 Citroen Seat Heater Suddenly Not Working

[Edson Achaca]

Hi I have a 2012 Citroen DS5 Diesel and suddenly both of the seat heater stoped working so I took to a technician and he said he followed the wires all the way up to the seats and there were electric current but only up to the seat heater control module (picture attached) that goes under the seat but there were no electric current coming out of the modules so he suggested that the modules were damaged so I imported two new aftermarket modules from China (picture attached) and fitted but it still not working I don’t know what can it be and how to get it sorted.

Seeing as both of the heated seats have gone together, I doubt it will be the control units. It's more likely to be a fuse. Both heated seats are controlled by fuse F9 in the BFH3 unit here:

Ignore this being a left hand drive picture, the fuse location will be in the same place, so make sure you are in the right module as there care several fuse boxes there that can have the same fuse numbers.

This is the fuse where I have marked it in yellow:
