First have the radiator flushed in case their is trash that is causing blockage in the water system which is about $70.00. Next if that is checked and all is good the blend door could be broke and not switching from hot to cold when the temp select is adjusted common problem on these guys and you can get a stainless steel replacement for the plastic factory at heatertreaters.com $129.00. And if that needs to be done the dash must come out to replace the door. Heater Core could be busted. Ford has a fix now that the water system needs a restricting piece in the line for the heater core so the pressure does not bust the heater cores. to replace the heater core or blend door is about $700.00. Heater cores $40.00. I know this because I just done this to my 98 xp.
