Actually, I found today that it may not be the center pod at all.

I had the car in economy mode and set the climate control know all the way to minimum. According to the manual, this should have it blowing outside air in at blower speed 4 (the blower was set to automatic). Nothing happened. I put the blower on high. Nothing happened.
Once the engine warmed up, however, it started blowing warm air that seemed like it was heating up, the standard behavior for when the climate control system is trying to heat the car.
WHAT THE??????

Now I'm really lost.... What could be wrong here?
Must be a control system failure somewhere, but I don't know how this part of the system operates. I know that depending on the mode, the system applies current to switches that allow vacuum pressure to the flaps and actvate the fan, but I don't know what is applying the current to those switches.
If I am wrong, please correct me. I know I'm a noob and I'm trying to learn.
