heat troubles

1994 f-150 6cy 4.9, 4x4 with A/C, My heater will not blow hot air, not even warm air. Changed thermostat, flushed heater core. both hoses going to heater core are hot to the touch, truck runs at normal temperature, never overheats. Heater core looks brand new from the outside. Pleeease help, live in northwestern PA, its 20 degrees here.

If you think your heater core is fine, try looking at the heater controls. Maybe the blending door is stuck open or the swithches aren't working.

blend door functions correctly, hot to cold switch on dashboard works i think, when you switch it to a/c it works.
