Hi Justin;
You are not going to like reading this answer to your heater clicking noise problem. Here we go.....
You are unfortunately having a "Blend Door Actuator" problem. A major headache for many Explorer/Mountaineer owners.
The actuator is not moving the blend door in the direction to receive hot air from your heater core.
Repair is $1000.00+. A very large portion of the high cost is for labor. The whole dash needs to be removed. THIS IS "NO" B.S.!!
Some "idiot" design engineers had plastic used in a portion of the assembly. This piece of "plastic" becomes brittle when subjected to "heat"!!
I am very surprised Ford/Lincoln/Mercury has not had the problem corrected over the past 10+ years.
There is a quick fix for it for those that can do the work themselves and save money.

Sorry for the bad news;
