Why is my Heater and defroster not blowing hot air and the heater making a clicking sound on a 1997 Ford Explorer?

The clicking sound is coming from the actuator motor that controls the blend door. It's common for the connector to the plastic blend door to break, causing this symptom. This door regulates the amount of air that is diverted through the heater core and depending on how it breaks, it can also cause strange air flow problems.
This is a very common failure on this model and the fix from the dealer requires removing the plenum box and replacing the air flow components. This is a labor intensive process and expect to pay around a thousand dollars for the fix. There is an aftermarket kit that accomplishes the same fix and replaces the plastic components with a metal replacement. It won't break again and is much much less expensive than the Ford method.

What makes your windows keep fogging up even with the defroster on a 1992 Bonneville?
Your heater core is leaking in it's housing box and blowing moist air through the heater/defroster. Try bardall radiator stop leak. If no help, install new heater core. Chuck.
Does a broken thermostat cause the defroster inside your car to put frost on your inside window instead of remove it?
If the defroster is blowing hot air and it is still leaving moisture on the inside of the windshield, the heater core may be leaking coolant causing that condition. If the defroster is blowing cold air it could be the cooling system is low on coolant, or the thermostat is stuck open or the heater core is plugged up or the temp blend door has a malfunction.

Where is the defroster in a car?
the defroster is actually your a/c. it doesn't run much when it's cold outside but it works with your heater to remove the moisture from inside the car. blowing warm dry air on the windshield. just like it removes the moisture (humidity) from inside the car in the summer. the difference is the temp. you have it on. even if the a/c don't work, the heater will still do the job, just not quite as well.
