Question 94 Chevy Truck AC Quit

The AC in my truck just suddenly stopped working one afternoon. When it happened the whole system shut down and the AC control unit on the dash went blank. Just like someone flipped a switch off. I thought the AC control unit had given up the ghost so I got another one. Installed the new unit then tried it out and ....nothing. At this point I figure the new unit is bad or something else is a problem. Most likely it is something else but I am not sure where to begin. I pulled the glove box out and see a few relays back there but I can find nothing that tells me if any of them are AC related. Any suggestions are greatly appreciated.

the whole display went blank? how aboutthe blower does it still work
start by checking all fuses as it sounds as if you have lost power to the control head.

The whole system just stopped. Display does not show any lights at all. I thought it was a fuse at first but they all seem OK.
