Your 1997 escort only heats when you are not driving?
Chances are your thermostat is stuck open. Your cars thermostat sits in a coolant passage. When the car is running your coolant begins to heat up, and at a certain temperature your thermostat opens up and lets coolant flow to the radiator to dispel the heat of the engine to the air. When your thermostat is stuck open, instead of the coolant staying in the engine until it heats up it is constantly circulating through the radiator transferring heat to the atmosphere. When your cars sits still it heats up because the amount of air passing through the radiator is minimal, but as you begin to drive the air flow is increased.

Perhaps a bad thermostat and/or a heater core

How does a thermostat control the amount of heat being given off by iron?
the thermostat heats up and is spring loaded when there is enough heat it will close and stop the heating element, when it cools it opens again and turns the heat back on, hope this helps
Why is your car overheating and has not hot air in car?
No heat in your car may be from your water pump going out and not feeding your heater core with enough water to produce heat. First remove your thermostat and see if your car stops over heating. If it doesnt, then you need to replace your water pump. Hopefully you havent cracked your heads. If your car doesnt over heat after removing the thermostat, but you still have no heat in the car. Then its your heater core that needs replacing. Always replace your thermostat whenever replacing the water pump.

What should you check first if you have no leak and changed the thermostat in 97 escort and have no heat?
I had no heat in my escort either. A new thermostat, cooling system flush, new heater core, another new thermostat, ect. but nothing worked. Still only slightly warm air from the vents. The thermostat housing has a thermostat bypass in it. This bypass is always circulating coolant through your radiator. I plugged mine off with a thermostat gasket and now my car heats and blows hot air with no complications. Good luck.

How can you tell if the thermostat is going out?
Vehicle takes an excessive time to attain normal operating temperature Heat not HOT with coolant full - thermostat not closing properly Vehicle heats up too soon - No heat with coolant full Coolant boils out of reservoir or top of radiator - thermostat not opening
