try the bend door
Thermostat opening too soon? Heater air bound and needs to be bled
Mercury Mountaineers have a "blend" door in the heater box. It is probably malfunctioning. You can find more info by searching for Ford + "blend door" or "no Heat"
whats the answer
Check the blend door system. The door controls the air flow under the dash, and can cause cold air to come out.

Well, this could be a variety of problems, including the thermostat. Check fluid levels. See if your water pump is leaking. Heater core lines may be clogged. Flush the system, and CHANGE the thermostat. Try to get all the air out of the system. I would have a hard time believing that if you are only blowing cold air, and your engine is responding correctly and the idle is not going up and down, your heater core is probably blocked.
Heaters come on and off the keep the room at a particular temperature. If you don't want it to come on and off turn the switch to off. Don't keep it on auto or fan.
