my ford fiesta fan heater only blows out hot air,can anyone help?

the resistor controls the speed of fan,so if fan only worked at full capacity, if resistor was faulty. the reason the fan only blows hot, is the control side of hot air coming through fan it may be that the hot water in matrix is not being stopped could be, heater valve or direcional flaps good luck

When you say resistor I am thinking relay. Resistor,s lower amperage. At any rate, Ford has electric switchs for setting
hot and cold adjustments. Check your fuse box and replace any and all burnt fuse's. There also is a power distribution box in the engine compartment.
Typically the wiring is set up to isolate problems but at the same time its not perfect. Why was the resistor changed and
what was the original problem?
