Air conditioner on 2004 Hummer H2

The panel of the air conditioner is not working. It does not turn on. In my beleve it has to be a electrical problem realed withthe fuses. Can you please tell me what could be happening.

The air conditioning fuses are located in the fuse box under the hood. The fuses are marked Blower (40 Amp) and HVAC/ECAS (10 Amp).
