Default ac/heater do not work

Everything lights up on my dash when I turn on the ac or heater. But nothing works. Outside temperature lights up, fan displays when I turn up the fan to hi, when I turn up and down the temperature it shows movement, but nothing.
Any ideas

This is a situation where you need to run the diagnostics to get the HVAC codes.

Have you checked all the related fuses for the climate control system?

I am not the best at reading prints. It looks like I should be checking for three (3) fuses related to the HVAC system, is that correct?
Also, thank you so much for the help.

Sorry for the confusion. I am saying everything lights up on the control panel on the dash. I can see the outside temperature, and when I function all the ***** and switches, every display moves accordingly, but I have no heat or ac. Absolutely nothing comes out of the vents. I put a piece of tissue paper on the deforester vents, and no movement when I turn the deforester on or off. I hope this helps me explain my issues.
Again, thank you everyone for the support and feedback

So your blower fan is not operating...if you have a DVOM can you look at the wiring diagram (blower motor control module) above and try to diagnose this ??...if not find an auto-electric shop in your area and they should be able to fix it...other than a blown fuse this may be a little difficult to diagnose if you do not have basic electrical knowledge.
