Why doesn't the heater work on my Ford Fiesta?

I've started having issues with manual heating on my 2011 Ford Fiesta.
The manual heating blower on level 1,2,3 does not work at all (neither cold and hot air blowing) but it works on level 4. I would appreciate any advice on the cause of the problem and approximate costs of repair?

Failed heater motor blower, possibly because of water ingress. DO NOT SIMPLY REPLACE THE HEATER RESISTOR OR YOU COULD CAUSE A VAUXHALL ZAFIRA TYPE FIRE.
