Narrative:

Smoke started coming out of cockpit and cabin wemacs at about FL330 during climb. Declared emergency, turned toward kind and started down. Turned cabin blower off, pulled breaker and smoke ceased. Uneventful landing. Callback conversation with reporter revealed the following information: analyst called reporter because of inability of any analyst to decipher the word 'wemacs' which reporter had used in his narrative. It is the name of the air vents in the lear 55. As flight crew suspected, the cabin blower motor had malfunctioned, indeed fried itself. Reporter pleased that this ended as a 'non incident' for flight crew.
