Factory A/C & Heater Help

[big dump]

Thanks for the input guys. Jim, the hose is actually cracked, it looks like from the picture that the hose is still somewhat intact, however it's actually broken off and the molded end (flanged end) is still in the hole in the blower motor. Anyone know where I can track a new one down? As far as the wiring, I think that I'm going to create a dedicated ground somewhere on the firewall, because I think that's what led to the whole burn up.
