I have a 2006 GMC YUKON DENALI XL and the front A/C & Heat

Customer Question

I have a 2006 GMC YUKON DENALI XL and the front A/C & Heat isn't working, I just replaced the front / forward digital control and nothing the blower would occasional spin but never on command and now it doesn't do it at all (no front blower even after replacing the digital controls for the heat, air, defroster the only this I can say is that regardless of it not working and changing 2 sets of the controls is that with both controls (old and new one) you would still hear a very faint hiss throughout the front vents even after the retained electricity is used or key is out of ignition, used and everything was completely off, even if the battery is disconnected !?!?!.
I submitted this question yesterday but I have no idea what happened to it !?!?!? Since I have no A/C down here in FL I'm going to try and fix this as fast as I can if you could be kind enough provide me with part numbers and diagramseee well as part numbers and diagrams would be most also appreciated. Thanks so much Paul
FYI - It is NOT blowing HOT AIR thru the front vents is blowing (as so many of these do when the actuators go bad ?!?) NO AIR is being forces thru the blower at any speed or at any temperature.
