Heater ..all settings, temperatures, and speed, including off....makes a click. 2 times every idk 20 seconds. When I change the setting n blend doors/ actuator ( not sure if this is right terminology but when setting changes and you hear doors move)moves sometimes that first set of clucks is a lot louder but then is the same. Pretty much it is just the same no matter what but sometimes when I change it it's louder at 1st.any ideas?

Not sure how the escape blend doors are actuated... I know on a 97 f-150 I had I would get this clicking noise when selecting different zones. The molded end of blend door where the vacuum motor turned it was cracked down the side, so it would skip a tooth, then got to where blend door stopped working. Took me and a buddy a whole weekend to open the dash to get to it. New one had a support sleeve around this area of blend door.

I checked the SI. The actuators are vacuum controlled.

welcome to the city, J.
you have your terminologies correct
It almost sounds like you have mouse debris caught in your system.
First thing I would try is removing fuses, to see which system is actually in play.
when you are changing from floor heat to defrost, does that occur?
I would strongly recommend following your ears, if it is that audible, it should lead you right to it.

Take a length of something like a garden hose. One end to the ear, the other end, use to pinpoint the noise. This works well.

Do you hear the noise with the key on, engine off?
