See my answer to your ?? over on AACA. Someone here may also have some ideas, but my money's on that compressor clutch switch on the control head.

 

Does it blow when set to AC modes? If so check the wiring leading to the AC compressor clutch. Unplug it from the compressor and put an ohmmeter across the two wires. Let us know what you get.
