Red face 4X4 not working...

Hey All,
I have recieved 14 inches of snow in the last 2 days and heading out to go to work with nothing but a truck that doesnt go easily. I attempted to put it in $ wheel drive and to my surprise, ended up with nothing, No lights in the dash lit up, hubs didnt lock and transfer case didnt shift. With that being said, I have read a couple other posts regarding the vacuum pump, tested it all is well. Manually locked my hubs and still nothing, I waited the minute or so stated for the ESOF in the owners manual and still nothing. Front tires most definately made full rotations. I tore my dash apart and got to the back of the switch and unplugged it, with a continuity tester i found no power from any of the 4 leads on the pig tail. I got underneath and checked for lose connections all is tight, Had someone switching while i was underneath and no result. I Removed both pigtails from the transfer case no power to them either. I have tried anything i can think of, no blown fuses. Any help will be greatly appreciated!
