Doesn't the 79 300SD come with the evil ACC 2 servo?
Answered my own question: yes it is. I've seen all sorts of nightmares with this system. Could the servo be drawing more power instead of the blower motor? I know common sense dictates blower motor and/or aux pump but I wouldn't rule out the whole servo box itself. I would disconnect the blower motor first and play with the HVAC system to make sure the servo isn't the culprit.

FIXED! It was in fact the blower motor. I took one out of another car and wired it up and no melting fuse and it doesn't even get hot. I also fixed the Hi Lo Bi controller. The vacuum connection on the back of the climate control unit was completely disconnected. Hooked it back up and everything is perfect.
