ford fiesta p reg - Heater always on

[TURLS]

i have had this little 1250 auto for a couple of months, nice little car but but can not get the heater to work at the right temp, it is only giving me hot air although i have it on the blue, this is just about bearable in the winter with the windows open but i don,t think i will last the summer without finding a way to sort it out, am i missing something ?
