Technical Heater blower

[Clarendon]

Hi guys could anyone help me out ? . I have a fiat bravo 1.4 tjet 150 sport. The problem is I am having problems with my heater blowers. All the panel lights are working fine but when I put the blowers on nothing is working , never had any problems before as the just stopped working , no burning smell . Could there be 2 different fuses or has the fan just stopped working and a replacement needed. Any help would be much appreciated guys
