Heater blower blew and now nothing works

[mwrobo]

My 79 C10 just couldn't be happy with that new trans last week. The heater blower blew yesterday and nothing works. No lights, no engine turn over, nothing. The wires from the heater fan were cooked. I guess there was a problem of metal to wire, after I replaced the old fan back. Now I have a new battery and still no power, nothing. All the fuses look good, the resistor by the blower doesn't look good. I thought I might replace the ignition coil. I just can't imagine that the blower line is hijacking my hole electric system. Any ideas.... Thanks for your help!
