Help, wont' go into 4x4 and it's snowing!!!

[NSTAG8R]

I juse went out to get a bite to eat and put it into 4x4 high on my swith, nothing, I usually hear a click from the glove box area then the light will come on the dash. No click, no light, I hope it's something as simple as a blown fuse or relay , i don't have a Owner's Manual so I don't know which fuse operates it, please help it's snowing like hell and I have to be at work tomorrow

my 01 explorer is fuse #10...it also controls blinkers, rear defrost, overhead temp display...many other things...if the fuse is blown you will find that other things arent working...which is the problem i am havin right now..the fuse keeps blowing

If the fuse keeps blowing there is obviously a bad power/ground wire somewhere. Might be time to grab the old multi-meter and do some testing.
