fix my ford heater?

Hi Chris- you will need to change the heater control valve which is located behind the bulkhead of the engine near the windsreen wiper motor. It has two pipes going into it and two coming out. The valve is probably stuck hence it is only blowing hot air. You could alternatively take it apart and clean it out so it does not stick anymore. It is easy to do, only 4 screw to remove the valve
