I have two symptoms that seem to be related:
1) A clicking sound, coming from below my dash. It sounds like a gear thats trying to turn, but can't so it clicks backward, only to try it again. It consistent too, like a heartbeat. Specifically, it is around the area where the radio wiring is.
2) My heater is not working. It blows air out, but it's not warm. I've verified absolutely that I do not have the A/C on by accident. The air does not feel cold per say, but it feels like air from outside being blown inside.
I've checked the fuses, and that doesn't seem to be the issue. Any help is appreciated. While I don't expect to be able to fix this myself, unless it's something reasonably simple, I would like to know what to expect should I take it to a mechanic. Thanks for your time.

The sound you are hearing is the blend door actuator trying to switch from hot to cold. You have a broken or jammed blend door by the sounds of it.

Electric relay is trying to open the heat door to the heater core without success. Try moving the door manually if you can get to it. They do rust up at times.
If that does not work, find the relay and replace it. Your local library should have a chiltons repair manual for it

Ford uses vacuum switches on the heater system. Sounds like you have one that failed. Use an old stethoscope or a rubber tube to find the noise and then replace the switch

Here is how to change the blend actuator for future reference.
