Hi the mother in law has a Ka sport and the heater is only blowing out cold air! There is no water loss. Does anyone have any idea on what could be the problem please? Cheers

 

Hi mate theres a wee valve in behind the dash. Very common on kas and fiestas. Nothing to worry about.

 

Heater Control Valve
I'd get it done asap, I had to do it on both my fiestas, first one snapped and emptied all the coolant out, second one just failed, only blow hot air, and then the car overheated...
Oh, it's not behind the dash either, it's in the engine compartment, at the back.

 

heater control valve mate,fitted loads of them,get 1 from the main dealer tho as the after market ones dont last

 

Thanks for your replies guys, cheers!
