Fans not working

[Halon]

OK well the car finally started up today! I installed a 14 and a 10" slim fan. Here's what I did, in the order I did it. I had my dad turn on the AC. The AC fan kicks on like a champ! So we turn the ac off, let the temp rise and wait for the 14" to turn on. It never does. I wonder wtf, is it the wiring or the fan. So I plugged the 14" to the AC plug, and tell my dad to turn on the AC and see if the fan kicks on because we know the AC wiring works because it just worked with the 10". He turns on the AC, nothing. Now I hook up a battery to it to see if it will spin. Still doesn't work. OK so the 14" fan is bad, crappy!! So now I hook the stuff back up, but I have no voltage at the AC fan now. Apparently whatever was wrong with the 14" killed something in the AC circuit when I hooked it up to the AC plug. I checked the fuse on the battery for the RAD FAN. It's blown. I replace it, still no voltage at the AC plug. I swap the RAD FAN relay out with another one, no change. So now I'm not sure wtf is wrong. Any input on this?
