Problem solved.

I swapped out the climate control panel (I assume that is what it is called, it has all of the push buttons for selecting fan speed, etc) with one I had on the shelf, took care of the problem, and now all of my fan buttons and directions work again.

I had the console apart while I was installing my XM radio, the key was on but the engine was no running, I suddenly heard the clicking sound and heard what sounded like a vent being rapidly opened and closed (really fast). For the heck off of it I turned the temperature dial and the noise stopped, but it couldn't get it took start again. All during the life of this problem, none of my climate control buttons worked at all, that's why I decided to try replacing it.


Now onto the rest of my list.
