Ford fiesta mark V blowing hot air all the time

[Driver Rider]

Hi,

ive got a 2000 x reg 1.25 ghia fiesta and it runs fine the only problem is that the car keeps blowing hot air into the cabin even when the heater is off and the thermostat is turned to cold. I really don't know why this is and wanted to know if anyone could give me some helpful pointers before i take it to the mechanic!

thanks in advance!
