Default More climate control issues...

This is my second post on this problem. In the beginning I had no control over my HVAC and the AC and RECIRC lights were blinking so I replaced the control unit. That worked (but the lights were still blinking) and I now had control and everything worked fine for a while. Now all of the sudden I am back to square one with absolutely no control over the system. No buttons or slides work at all. I checked the codes and they are below:

315 - Recirculation Damper Motor Shorted to ground or power
323 - Ventilation Damper Motor Active too long
325 - Recirculation Damper Motor Active too long
411 - Pass. Comp. Fan Overcurrent or seized fan
414 - Driver's side temp sensor intake fan seized

Being that there are 5 different codes I don't know where to start. I have looked around the forum but every post I can find the person has some kind of control over the unit. Once again I have no control at all. Thank you so very much for any help that you can provide.

I reset my DTC last night and now I'm only getting the one fault:

325 - Recirculation Damper Motor Active too long

What would that one fault be? I here a faint click sound when I try to turn the fan on or up. Again, nothing is working at all. Sorry about the double posts, I forgot I already replied to the earlier one. Thanks in advance for any help you can give me.
