I have a 2WD 1997 Ford F150 4.6L and for some reason the Heater blow cold air. I can drive the truck all day and get the truck around normal temp and it will still blow cold. it shows no signs of getting warm or hot when im driving or if im parked. What could this be??

MrMustang; The very first thing to check would be coolant level. If the level is low, you won't get hot coolant through the heater core. If that is okay, take actual engine temperature. It should be running at 195F, minimum (thermostat stuck open). If that is okay, check the temperature of the heater hoses (heater core blockage). The should be of equal temp. If all of the above is okay, buy a Dodge. No, just kidding. Could be a blend door problem. Let us know what you find, then we can proceed further, if need be.
