Sometimes if you jiggle a blower motor it may run? The vibrations may cause the brushes to make contact, intermittently. With blower motor installed, check for voltage and ground, controls turned on, violet wire is voltage, black wire is ground.
Your directional actuator doors appear to be vacuum controlled. Most vehicles I work on, if vacuum is lost, it defaults to defrost.
